Yaoi

Need help finding a yaoi manga of two roommates, one is a man slut and the other is gay. Man slut and gay guy used to go to high school together and played football, until gay dude got hurt, but he didn't care because he said he wanted to quit playing after high school anyways. So they got to college and room together, man slut then catches gay dude running his hand through his hair as he is doing the sexy with another guy. Man slut then wants some of the action and pesters gay dude for some sexy time, and their first sexual moment is in the bath tub. That's what I remember from the first chapter. Please help!
