Ho,There are two issues: did in fact homosexual sex occur alongside heterosexual sex?
The simple existence of descendants in my view does not preclude the regular or even universal practice of homosexual sex. In our most closely-related species, bonobos, this is the case.
The second issue raised by your question is: how could there possibly be an adaptive advantage to homosexual sex, especially if it led to fewer descendants, or a smaller gene pool? At this point we move past observation to hypothesis. My suggestion, which answers your question, is that homosexuals, without the need to care for children of their own, or with fewer children of their own, are available in human groups to provide support for childcare, and other services to the group, thereby strengthening the chances of survival of their close genetic relatives.
Homosexual sex in early human history, or our history before we were human, was clearly not a dead end, and could have led to our very existence. It was clearly not a dead end since the universal practice of homosexuality in human society suggests it has always happened, and our close relatives like it even more than we do. It may have led to our very existence by helping support a group of non-parenting individuals who helped strengthen the group, in much the same way that celibate clergy strengthen the Church.
If you postulate that there were first a male and a female that then created another human being then heterosexual sex preceeded any homosexual activity by default. The question then becomes when did this perverse activity begin and I don’t think anyone knows.
Your consideration of what the purpose of homosexuality might be is at odds with the history of laws against homosexuality. They were not a welcome group.
