Pretty straightforward: Horny guy(s) getting laid regularly with multiple different ladies and there's something of a (fantasy/sci-fi) plot over multiple volumes.

The more openly and shamelessly pervy and horny he is, the better. Like Ral from Ral Grad--he likes it, he wants it, he shows it, he says it, he gets it--but with the fun stuff on-page and not just implied.

Extra bonus if there’s some bi/homoerotic content too, but not necessary.

Thank you.
