Help I can't remember the name of this bl manga

I read it before on this site, but I can't find it anymore because I don't add it to the list. The mc and ml are both tops. Mc finds vids of ml porn vids. ML has a reputation for being skilled in bed and also for not sleeping with the same person twice. Mc ask for Ml advice on how to top. They fooled around but don't exactly have penetration. Then things happened and ml and mc have to sleep with 2 bottoms, one a virgin. They did it in the same room and both got jealous because of them sleeping with another person. Then ml took mc away and confess their feelings and slept together. It's a short manga. I think mc is some sort of prince but I might be wrong on this detail.
