I have always been attracted to girls from since i could remember but did not act on that thought until i turned 17. I met this guy who i immediately got into a sexual relationship with but we never became boyfriend or girlfriend, out of all the guys i messed with he was the only one who i clicked with sexually and mentally i mean sex with dude is insane i did not bother to look elsewhere but i was young and i also wanted someone more of my age who i could hang with all the time you know things that young teenagers look forward to doing cause he was 25 at the time and had a daughter and other issues to deal with. I kind of moved on to other guys but would always make time to see him when he was available. Now im 20 years old and i met this girl who now is my fiancee we live together basically what is hers is mines and what is mines is hers we have been together almost two years now and our relationship is kind of down hill because i have been cheating on her with this guy. this did not happen until 6 months into the relationship everything was fine before and then i jsut felt myself craving his touch his lips hiss kisses and everything else. Things have gotten so bad with me that all i can do is think about him even when having sex with my girl i fantasize about him. I need to know should i tell him how i truly feel about him or is something wrong with me i need help? i think iam obsessesed with him and i need to stop and get my mind right.
