This is a short update to pass on an article that I recently read about kissing ...
Back in November I pledged to give up masturbation. Since then my wife has become very keen to kiss me as often as she can. My guess is that my testosterone levels have risen and she is getting some of it from me when we kiss.
For those who do not have time to read the article, it basically says that kissing has two key benefits. One is that both partners get a boost of oxytocin. The other is that the male passes some testosterone to the female in his saliva. This boosts her interest in sex. Testosterone controls the libido in both men and women, but men naturally have more of it.
So, kissing is a great way to get in the mood for sex. It relaxes both of you, and raises her level of sex hormones.
