What is it called?

There is this Yaoi manga that I really want to reread but I can't remember the title. It is about two friends that looked good and would go out together and get girls. One day the went to a hotel together and had sex. They would keep having sex but one day something happen. I forgot I just know one of the guys was sad and wanted to have sex and so the guy brought him to this sex bar thing. And he said if you turn me on I'll have sex. That is all I remember.
