You guys seem to me very confused about sex. Let me try to enlighten you a bit.
First of all, you can CALL yourself whatever you want. Gay, Bisexual, Straight, or anything else (I recently heard the amusing term "heteroflexible"!). However you choose to identify is a matter of personal choice, not a matter of legal, social, or clinical/medical terminology. So trying to tell someone else "Hey, if you do/think/desire that, then you're gay/straight/bi/etc." is ridiculous.
Another thing being tossed around in this discussion with no apparent understanding is that there's a difference between a Sexual Orientation and a fetish. Fetishes create desires for sexual behavior that is unrelated to the person or persons involved. For instance, many men love breasts, but someone with a fetish for breasts enjoys them to a much stronger degree, and to the almost total exclusion of the woman who "owns" them. In fact, if it were possible, he'd prefer that she wasn't even there; of course, she must be, so he tolerates it. Some men with breast fetishes even hire prostitutes and instruct them to be silent, to not move, and to simply lay or stand there as they please themselves with the breasts in various ways.
The same can be said for a functionally and self-described gay/homosexual man who has a fetish for pussy. He may have formed this fetish in any number of ways, but in the cases that have been described in the scientific literature, the man usually reports that he thinks of other men's penises entering the vagina in question, and/or imagines that this may happen in the future. This allows him to have a homosexual experience with the imagined male, using the body of the woman. Other men also report that they simply have a fetish for the unique feeling of a putting their tongue or penis into a vagina, but do not think of this as sex with the woman who "owns" the vagina.
Similarly (and more commonly) gay men have reported fetishes for breasts, buttocks, feet, and other female body parts, all the while insisting that they are homosexual in every other way.
Nature has provided us with incredible diversity in our sexuality, both within a single person, across the lifespan, and across our species. Frantically applying strict labels and the subsequent judgments that often come with them, is a waste of time.
