re: “Is it the almighty prostate? Or is everyone bisexual at heart?”

Why should it necessarily be either?

The number of people (of either sex), who are able to achieve an orgasm via one of the two sexes, and not the other (under the right circumstances), is probably at about zero percent. By certain scholarly individuals’ reckoning, that makes us all bisexual. Whether or not we desire to choose to experiment with the same (or both), sexes, is another matter altogether.

I can’t see that the desire to experience pegging necessarily has to be due to bisexuality or the “almighty prostate” either one. After all, millions (probably billions) of women do (or could), experience great pleasure (or even orgasm), through anal penetration, why should males be any different?

Besides all of the other nerves (other than the prostate that is…), which surround the anal area and respond to stimulation, certainly men might even enjoy the mere psychological aspects of sexual activity with a sexually aggressive woman (such as a dominatrix), without having either to involve the prostate, or to secretly desire sex with another male.

A fetish for erotic humiliation may in some cases be an attraction.

An empathic curiosity surrounding what it’s like to experience sex as a woman, might be another reason, and surely that doesn’t have to necessarily denote a desire to be in a relationship with another male.

Just because some (an not ALL, by-the-way), male homosexuals practice anal intercourse, that doesn’t mean that anal sex should be a homosexually identified behavior any more than because a man enjoys receiving oral sex (a practice also enjoyed by male homosexuals), that his heterosexuality should be suspect. Same thing with hand-jobs. Homosexual men often enjoy this practice (which involves orgasms without the inclusion of vaginas), but surely this doesn’t mean that all men who enjoy the handiwork of their wives or girlfriends (or who masturbate themselves!), are gay or bisexual.

Many lesbians enjoy strap-on sex, with either faithfully replicated penis-shaped dildoes, or merely phallus-like abstractions. Just because nature has designed their vaginas to respond well to the physical stimulation provided by phallic-shaped objects, doesn’t mean that they want sex with a man either.
