That brings a hole new meaning to

"FRUITY Flies"

I attempt to copulate with males' heads all the time.

Nothing unnatural about it, same-sex behavior spans the animal kingdom. Prejudice against it, or considering it unnatural is really religious or patriarchal ideology. Consensual sex has many functions not just reproduction. It helps form bonds which make for evolutionary advantage. Most of the human population is capable of it, but it is so heavily penalized, most people hide the behavior if they do it. It's only since the gay liberation movement that those horrible attitudes have begun tochange

It also happens when flies have fru mutants (fru is necessary for male courtship behaviour)

Homosexual behavior isn't unnatural.

Homosexuality is a hormonal disorder found in animals too...whats the point?
