Some, but not a ton. You already had anon describe his, and we had another guy here playing OaTs with freeform lewd tacked on. For published games, I think it's telling of the fundamental challenges to lewd sci-fi that most of them are closer to post-human cyberpunk than the hard-ish near-future, space opera or speculative fiction we usually think of for sci-fi. Just on the combat angle, "loser gets fucked" is about as traditional as concepts get, but moving out of fantasy usually involves a shift to ranged combat, which adds some oddness to the base concept, but also that I think we have an easier time just accepting the debilitating but non-life-threatening wounds are the norm for swords and clubs than we do for gunshot wounds. There's a Kill Team conversion floating around here somewhere that works around that by placing a ranged victim force against a melee-focused aggressor team, but that highlights another challenge of ranged combat, in that it pressures the system into wargaming territory by needing to track distances, cover, and multiple playing pieces so that they can support each other. Without those, it becomes a game of "You have X turns to land Y hits before they're on top of you, roll for mindbreak". Melee works in an abstract moshpit in a way that gunplay just doesn't. You could work around this by going John Carter of Mars with it, but is that "true" sci-fi, or fantasy with a paint job? Maybe Dune would make a good basis.
