ive had issues dealing with my gf's sexually active past and her partners she has been with. i was a virgin when i met her - however, i get really turned on by thinkin about her bein with other guys n thinkin about what they do n how she is with them. i also fantasize about many guys doin her at once like 3 on 1..etc. or even watchin her while other guys do her. i know in reality i would never go thro with this and it bothers me about her sexually active past. but why is it that im really turned on when i think about this? everytime i masterbate is usually to some thought of her bein with a few other guys at once..
