Hi

I hope somebody can help me because i can't think of the name of a certain manga. I thought of it after seeing Kisaragi Gunma's "suki ni nattara icchokusen". I kinda feel they are similar

So here's what i know
It's english... or at least partly.
It's manga sized and the story in question is a big part of it or encompasses the complete manga
There is a sex competition in the manga and the reward for winning is getting married naturally the main characters win this

If anybody knows this manga's name please let me know

Thanks in advance

This is the closest I can think of Gakuen Seikatsu.

Yes that's the one

Thank you
