Why does sex hurt for me?

Lupita • Violinist
So my boyfriend and I and are beginning to have sex, right. It's been atleast the 6th time and sex is still very painful. I make him enter slowly so it doesn't hurt, but when he's inside (he doesn't even go deep) it REALLY HURTS. I don't know if it has anything to do with lubrication because he enters fine and it slides right in, but him just being inside hurts badly. I'm patiently waiting for sex to get better, but at this point I don't even know if it will because him being inside just barely kills me.
