This is ridiculous, of course. We all know lots of masculine men who prefer to be the receiver when it comes to fucking. Many gay men find the experience of anal sex has a spiritual component to it. If you think of sex as an exchange of energy, male sexual energy is typically hard, driving and forceful. Taoists call this energy yang .
Anal sex is perhaps the primary way men can cultivate the corresponding energy, called yin .
It is easy to misidentify yang as male energy and yin as female. This is sexist oversimplification. Yin is soft, yielding, receptive, enfolding. In our culture, these are attributes that don t always come easily to men. Men who bottom in anal sex can be understood to be feeding their yin energy.
