Any harem like..

I like harem mangas, with multiple girls after a guy or uke guys after a seme guy and at first it was funny how the guy couldn't handle it but little by little the fact that the guy being chased constantly got nosebleeds/passed out/just plain didn't do anything started getting boring..

guess what i'm looking for is a manga where the guy being chased is able to handle it if not takes advantage of it

straight or yaoi harems don't matter either works, and the ecchi...er the better
