I live in a condo with my roommate. My roommate (29 years old) is a masterful PUA and has been doing game for years. Everytime he gets laid, I get VERY uncomfortable, and I don't know why. Almost every night he brings back a new girl, and I could hear them fucking in his thinwall bedroom. Can anybody explain why I feel so uncomfortable? What sort of psychological trigger is being played here? Am I being jealous?

Why am I so uncomfortable that my roommate fucks a new girl everyday?

I'm 24 years old.
