If you really want to blow his mind, play with his prostate -- a chestnut-sized pleasure center about three inches up the front wall of his anal canal -- by making a "come here" gesture with your finger.
Stimulating it will give you a little hint of what anal play can feel like.
While homosexual men definitely are open to this area, heterosexual men can easily encourage their female partners to help stimulate their down-there region, similar to how you might suggest anal sex.
In addition, it improves overall erectile function and increases seminal fluid and circulation.
Description: As an example? This point can't be emphasized enough.
