Should I have waited?

So I am 14 years old. I just moved to little rock Arkansas and I have been here around 5 months ago. So a couple weeks ago I had lost my virginity to this guy I barely knew. He told me I was cute and that he wanted to sleep with me and get together after. He came to my house and I did the deed. He hasn't talked to me since and last night he wanted to come over and "chill". What should I do?(please comment). I haven't told my mom yet and I don't know if I should? Should I have done it or waited?
