Dear Dr. Pezzi:
Thanks so much. I just wanted to let you know how much I have enjoyed
reading The Science of Sex. What an amazing resource! Thanks for
taking the time and effort to do the research, present it eloquently and
dispel the myths. In a world with so much disinformation, your writings are
very much appreciated.

I'm really enjoying the book.
I was skeptical as usual but this book is right up my alley. Very scientific
without being over my head.
This book completely blows away any other sex book, by a
country mile. To borrow an old European country saying: first comes this
book, then there's a loooooong stretch where there's nothing . . . then
there's a big pile of manure . . . then another long stretch of nothing . . .
then every other book on the market. Well, it's funnier in German. :-)
Anyway, you can go to any bookstore, and replace the entire sex section with
this book. Any sane publisher should jump on it, you can split the book into
ongoing volumes. Perhaps there is more profit in doing it this way, though I
don't know if the publicity a publisher could give could be matched. Getting
the book mentioned in good target audience media like Maxim or Stuff
would increase visibility a good deal as well. In any case, it's an awesome
product that can only grow.
You spoiled my whole weekend!
I bought the book on Thursday and then proceeded to get *nothing*
done until I finished it many hours later on Sunday! The
Science of Sex may have made me ineffective at getting my work done but it
made me much more effective with my lover. It was filled with great
information and real action items. I am very impressed and appreciative.

Hello Dr. Pezzi,
I got it and it looks like it is everything I hoped it would be. Money well
Dear Dr. Pezzi:
I assume from the size of the manuscript and the impeccable layout that you
intend to have it commercially bound and published at some point. I hope so,
because it is vastly superior to anything I have seen on the topic from a
medical view. As an example, though maybe not the best, the same day I stumbled
onto your site, I ordered a book on natural aphrodisiac supplements from a
self-proclaimed national sexpert (and evidently other-proclaimed as well, since
he has been interviewed on NBC Nightly News and in USA Today and Le Monde, among
others). The nicely bound 100-page book or booklet I got was a bland litany of
reputed aphrodisiacs and their claims, supported mainly by anecdotes and
days-long My Personal Experience which invariably led to a favorable review,
with only vaguely described "increased sexual interest" for most; telling me
more about his suggestibility than anything else. I realize I'm being way too
hard on the guy, who in all probability merely wanted to Keep It Simple. I have
nothing against anecdotes: contrary to the retort I once got from an attending
in school, anecdote is the singular of data; how could it be
otherwise? And the personal experience of a highly interested researcher is
always valuable; but in sexual matters, the placebo effect is so strong, it is
not enough. I don't know; I was just disappointed that so much of what is
printed on this subject is of a like character, whereas from such an expert I
would have expected authority, scholarship, sound criticism, integration, and
above all, creative insight. In short, I expected a book like yours! It's all
So when will we see you interviewed in Le Monde?

I'm in love with the kind of books
you write, Kevin. By all means keep up the good work. I have lots of books in my
bookcase, but quite frankly, yours really rank among those I'd rate as most
interesting. I sure am not disappointed.
I guess you're now close to age
48, yet your physical appearance looks to me (from the 2002 pics I saw from your
webpage) like you're in tiptop shape; your BMI, skin, your mind, etc. My
girlfriend had a look at the 2002 pic where it says you were 44ฝ, and she too
admitted you have good-looking skin and looked young. I see people in their
early 30s who look like they're in their late 40s, so calendar age is definitely
not the same as biological age. I may sound like I am layering it on thick, but
I'm simply granting you what's rightfully yours. You went deeper, worked harder
than other MDs, you went off the beaten track, and at the end of the day, it
pays off, so to this I say, way to go, well done, Kevinthere should be more
people like you out there.
Riviere-du-loup, Quebec, Canada
I've been trying the yohimbine...holy shiznit! A supplement that
actually works! I've been using it for less than a week, but the results are
incontrovertible. As I relate this, keep in my that I've had a cold for the
better part of the week, and feel generally pretty lousy. Nevertheless, when I
was talking to a woman at the office who flirts with me, I popped such a rod
that I had to hide it and explain away my laughter. ;-) I normally
encourage this process, since as you mention in the book, thoughts of sex can
increase testosterone levels, train erections, etc. But this was *rock* hard,
way out of the norm for casual flirting. That night I decided to masturbate just
to get to sleep easier, and noticed that when I was done I didn't feel the usual
"OK, I'm good for a few days" feeling. In fact I began to wonder if I could do
it again. I went for it again, and easily got the job done, total time between
attempts was a few minutes! Unthinkable! It could have been even sooner had I
thought of it. The next morning, I repeated the experiment again, and again was
able to go twice in rapid succession, where I'm normally a one-shot guy.
I also noticed that erections seemed to point a few degrees further north than
usual, and felt stiffer than usual, which of course is a great feeling. I was
able to quantitatively analyze the situation by using my vacuum pump. I have the
cylinder marked off with a permanent marker, so that any change in length at the
same pressure will be obvious. And there was the evidence: at the normal 4 in.
Hg., I was a quarter inch longer than normal, in a matter of days. I assume
circumference was even more affected, but this can only be explained by
increased pressure inside the penis, since the outside pressure was measured to
be the same. I can conclude that the yohimbine really does produce a larger,
stiffer erection, in addition to reducing refractory time and generally
increasing libido. And this at half the manufacturer's recommended dose, one
capsule a day instead of two. I noticed no other effects whatsoever. I don't
have a blood pressure cuff to see if my overall blood pressure is higher, or if
it's a penis-only effect. ;) I feel no tremors, nervousness, or any other
In regard to the book in general, great job, and I'm impressed as always with
the added material (note from Pezzi: this reader read an earlier
edition of this book). I think the book will be enormously valuable to
anyone with the wherewithal to actually take the advice in it. It could be
particularly valuable to women, who while they may be reluctantly aware of the
importance of bodyfat in general, may be completely oblivious to the fact that
vaginal quality is a big factor in relationships. Simply doing Kegel exercises
could make a major difference in attractiveness and resulting quality of life.
Sad to say, and an enviable thing for men, but a woman with a great body and
great vagina can write her own ticket. A woman who takes initiative there is one
in a thousand.
No one can complain that you don't tell it like it is, and explain what to do
about it. It's safe to say there won't be any other book out there to touch this
one for interest level, straight talk, and practical advice. Congratulations!
Hello Dr. Pezzi,
Thank you for the wonderful book, The Science of Sex! I have a
doctor's mindset and I really enjoyed reading your book very much. It
was a real pleasure to have something intellectual (and written by someone
very apt at that!) upon the subject of human sexuality! You clarified
several things for me, helped me to determine several supplements I should not
be taking (as a young man) and gave me many new insights into information
which I had no previous knowledge upon regarding this subject and similar
Before I read your book, I thought that your statement about it
discussing "things that Dr. Ruth and other sexologists have never considered"
was probably hype. However, I was intrigued by some of the topics you
listed, so I bought it anyway. I think I owe you an apology for doubting
you. Your book is packed with information that, as you said, you can't get
My wife and I have been reading one sex book after another for
years. We are always searching for new things to try out in the bedroom.
I agree with you that most authors tend to rehash what other authors have said,
because we don't learn many new facts from most books. But your book?
That could keep us busy for years!
Throughout my education and career, I've read many books.
I don't know exactly how many, but it's enough to fill half of my basement with
dozens of boxes. I can't recall ever being more thrilled by a book
exceeding my expectations than I have been with your book. The Science
of Sex is bound to be a classic, and THE manual for people seeking to
enhance their sex lives. Great job, doc.
Your discussion of tip condoms was worth ten times the price
of the book. It's enabled me to experience much more sexual pleasure.
I just wish that I'd known about this a decade ago!
Hello Dr. Pezzi,
Your cutting edge perspectives are fantastic!!
I experimented with several suggestions that are showcased in The Science of
Sex to fix my sexual sensory dysfunction and penile shrinkage (7.5 to 6.0
inches), perhaps induced by two cycles of Accutane. My brief story: 26
years old, healthy, athletic, hypogonadic with no sexual sensation when
ejaculating. Recently, I applied Androgel to my scrotum. I concur
with your results: larger erections, smooth/firm texture, there is
definitely an awakening. I sincerely appreciate your mind and care for
people's pursuit of happiness.
I ordered your e-book a few weeks ago and am really enjoying it.
It's a great book so far, with lots of interesting information.
I've been reading about sex in magazines and countless books
for most of my adult life (I'm now 51 years old). I thought that I knew a
lot, and I generally do not learn much from reading sex books because most
of the topics presented by the authors are things I've already read ten
times. Nevertheless, I am always on the prowl for new nuggets of useful
info. Most authors teach me a few new things, but you taught me a lot about
things I'd never before considered . . . but now that I have, I was
spellbound by your discussions. I am not a fan of e-books, so I never
imagined that I would read one as long as yours. However, your book was
extremely interesting. You know more about sex than ANYONE. I also like the
way you make it so easy to contact you. Getting in touch with an average
author is next to impossible. Thank you for writing such a superbly
informative book, and thank you for giving me in-depth answers to the
questions I submitted to you.
