Tweety, you seem to be looking at sexuality in too black/white of a manner. IMO, it is nothing concrete, and everyone is basically a shade of bi. Most people are just effectively "gay" or "straight" cause that's what becomes logistically sound. I'm no expert on this stuff, but I would say many if not most "straight" people have either some attraction to the same sex or at least a capacity to be attracted to the same sex.

So I don't think it's as simple as thinking "gay" people just stop reproducing. "Gay" is just a label, and not a concrete description of what's actually going on. There's no way to know exactly what traits will be selected for in the future. But, it's not exactly impossible for gay people to find a way to procreate today, and you can assume it's likely to only get easier in the future.

I have a loose theory (I guess it's sort of similar to the gay uncle thing) that the magical hand of evolution makes it so a being whose survival is more secured will have a higher capacity for same sex attraction as a defense against promiscuity. As your time preference is lowered, basically, you get more gay as a means of protecting against unwanted offspring. [img]/images/graemlins/ooo.gif[/img]

Then, if you do reproduce, it's increasingly more likely that you were in a position where you really wanted the child and are ready to be a great parent, thus increasing the likelihood that your offspring will make good decisions, thus perpetuating the cycle.

It makes sense in my head but it's sort of hard to put it in words. Feel free to flame my theory (pun very intended).
