And when she orgasms it spasms, which feels incredible. Paintings and etchings from Japan, China and Europe all depict men performing anal sex on women, as do ancient erotic drawings, sculpture and pottery from the Mediterranean and South America. In the Fifties, anal sex was reported by fewer than fifteen percent of the population. Anal is more about shaft stimulation than head stimulation so if makes for me at least and entirely different orgasm. With anal, I can go balls-deep without having to worry about hurting her. The key is to relax the sphincter muscle, as this is the gateway to the anal canal. When women do have anal sex, the overwhelming majority, do so at the request of their male partner. I have met a few women in my time that truly liked it and I think they liked it for the same reason. I wanted him to stop the whole time, but I was too scared to say anything until he asked me. The feeling that she is giving up some of her humility for my pleasure, and that I am doing to her as I please. Different and still amazing. Modern overall rates suggest that around a third of men have performed anal sex on a woman, and slightly fewer women have received anal sex. Also you get to goof up in there. In the past, oral sex was taboo, as unrelated to procreation, and today, it has become ubiquitous, engaged in by most people, though where it is still rare, it remains an intense fantasy. When a woman is willing to engage in anal sex with her lover, it is usually coming from a place of significant trust and love of her male partner. Men are sexually interested by variety, but aside from this, there is no relevant evolutionary argument, as anal sex of course produces no heirs.
