I never thought I knew so little about sex and about how to give a man enjoyment. You might laugh at me, but I thought that only gays loved anal sex. Indeed, I could not even suppose that a heterosexual man could love anal penetration! So can you imagine my reaction when my boyfriend asked me to insert my finger into his anus? I was really shocked. He realized I new nothing about male erogenous zones and explained to me a few things.
Men do love anal stimulation as anus is full of very sensitive nerve endings. However, this is not the most important thing. Male anus contains prostate which is very sensitive to sexual stimulation, perhaps as sensitive as the G-spot. So men love not only anal sex which implies that they penetrate the female partner's anus. As well they want to be penetrated anally, though many of them do not dare express this desire being afraid of the partner's reaction. I can't say they are wrong, I was shocked, why other woman should not?
