I just started dating this girl Cassie about 5 weeks ago and i've cheated on her twice already, I feel so bad and im not sure if I should tell her. What happened the first time: My friend Anna came over to my house and we hung out like usual and I was playing guitar when she just jumped on to me and we started maknig out and it lead to other things, I had no control over it and I didnt use my good judgement.2nd time: Last night my firend Sam(ex girlfriend of 8 months) called me and said she needed my help because she was upset. So I went to her house and we hung out, I made a phone call to my firend Andrea and while I was talking Sam just randomly started dry humping me, she tryed to kiss me numerous times and I avoided them, but as the night went on she kept trying to kiss me and temptation is the devil... I gave into her tempation, I explained to her that I was already guilty from cheating on Cassie the first time. But, she somehow persuaded me to do more.I know im a bad person for this because I really like Cassie, but if my friends are going to keep attacking me with sex, what am I supposed to do.
