In a January 2010 debate with Shmuley Boteach in Manhattan, Dennis said: “I was born with courage. I take no credit for my courage. To say some of the things I say takes courage because they go against prevailing opinion. I believe that if a wife says to her husband periodically, twice a year, ‘Honey, I know male nature, and I want you to know that I appreciate the fact that you remain faithful’ is terrific for a marriage.
“I don’t think it works exactly in both directions. I think there are things he should thank her for, but not necessarily fidelity. There are women who do battle to stay faithful, but I doubt that they are in good marriages. Men in good marriages do battle to stay faithful.”
“If we don’t agree on male nature, debate is useless. If we don’t acknowledge that male nature is variety oriented and stimulated with phenomenal ease, like seeing a thigh. That is not true for women. There are no ads featuring male thighs.”
“If a man doesn’t admit this battle [to stay faithful], he’s either lying to you or he’s asexual.”
“A man wants to know that his wife understands his sexual nature. Most men don’t tell their wives about it, which is why when I eventually write my book on male sexual nature, my working title is, ‘Your Husband is Not a Pervert’. The vast majority of men are afraid that their wives will think they are perverts if they open up about their sexual nature. So they shut down and then women wonder, ‘Why is my husband so quiet?’ Because he can’t freely talk about his nature without you thinking he’s a sicko. So I do it on their behalf. I’m the husband’s best friend.”
