I am a 20 year old man 21 in a few months and I have been doing really stupid things lately that I am ashamed of. In the last 4 months I have been talking to, hanging out with, and having sex with a 13 year old girl. She added me on facebook a while ago and recently she's been talking to me and it escalated into us hanging out and at some point she expressed that she wanted to have sex and we have been doing so since. I don't know what is wrong with me or why i have been doing this. I am ashamed and embarrassed of myself. I feel like if I cut this off she will get me in trouble and maybe I am deserving of it idk. I am terrified.
