Hi there.
There is a Manga I once read and I wanted to read it again and see how far the scanlatinos are by now, but I totally forgot it's name and which mangaka drew it.
The genres were at least Shoujo, School Life and Romance. Not sure, but it also might have been Smut.
Some guy transfered into a former all girls high school or something like that. And all the girls were really horny for him, but he didn't want to sleep with them so he made the most plain looking girl in the school his girlfriend, because that would keep the other girls away from him. Or something like that.... I hope someone knows which manga I'm talking about and can help me >.<
Thanks a lot in advance

It sounds like Gakuen Ouji.

Ooh yes! That's the one. Thank you so much!
