'My Boyfriend Still Thinks I'm A V*rg*n'

I am a 22-year-old university student. I came to university with my v**rg**n**ty intact. 

After being here for a few months, I am no longer a v**rg**n and I have had s**x with three different guys, none of them I can call my boyfriend. I have a boyfriend.

 He is five years older than I am. We were both Christians. We kissed but never had s***x. I can no longer consider myself a Christian. Whenever he calls me, I don't know what to talk to him about because I feel so guilty. I told him he should forget me because I have changed, but I didn't tell how I have. 

 

My roommate got me into drinking and having s***x with guys. One weekend my roommate had s****x with two different guys. We talked about it. Sometimes she goes to the guys' room and have s***x with them.

 I love her because she is good to me. I suffer from prémenstrual pain and she helps me during my time of the month. Sometimes I think she has made me a very bad girl. 

My boyfriend still thinks I am a v**rg**n. Should I still tell him I am not and he should take his mind off me?
