Without any emotions, love, etc. what really defines someone as a Lesbian instead of Bisexual, or a heterosexual from someone who's gay when talking strictly sex? In its most basic definition, does the sexual preference of a gay man imply that he doesn't like vaginal intercourse, or that a heterosexual female strictly only likes said intercourse an no other forms?
Was this supposed to be "deep" or something?
Because heterosexual males can "like" anal intercourse. They just don't like it with, you know, men.
There is no difficulty defining these without emotions, provided we use your own model of use of the word "like." From a mechanical standpoint, a heterosexual likes sex with members of the opposite sex. A homosexual, with the same. A bisexual, with both. Soem gays do not like anal, some lesbians do not like oral, some people like to dress up in elaborate costumes, but none of that matters to the core definition.
I'm sorry, maybe I just need more clarification here.
