Well said Don,

And to answer your question, Ake, about are homosexuals repulsed by the idea of straight sex, I don't think a lot about any type of sex. There are some women after whom I lust, in my mind. Would/could I actually have sex with them should the opportunity arise...I really don't know. Very probably yes

Most of my straight male friends - who are not screwed up and sexually insecure - are happy to admit to having similar thoughts in reverse.

When you rant on you really do tell us rather more than perhaps you even know yourself, about your hang-ups and insecurities. The rest of us are just getting on with life rather than developing unhealthy obsessions about others.
