I known this guy since 99 and i have had sexual relationship with him on and off. but we have stayed friends. The person i live with who is 69 is his aunt. I am 32. the guys is in his 50's. when i have sex i feel guilty during it and guilty afterwards but before it my hormones so go for it. I feel like i shouldn't have done it or i shouldn't be doing it . whats wrong with me?
