You can be on top, almost with all mobs, BUT, this is hard thing, because:
1) You must be horny (you only can getting horny when enemy's seduce\fucks you).
2) Enemy must be tired (out of stamina, not in battle state)
3) You must have some stock of stamina, for being on top, obviously
If you achive all this, you are alpha )
After some updates you can start wrestle, and if you have more stamina than that enemy, you can forced them into pron state. But if you don't be lucky, you are will be fucked...literally
