PAINFUL SEX

So I had chlamydia about 2 months ago, then was treated and then I ended up getting BV, which I just finished my antibiotics... so I have had this burning, and pain during sex once he starts entering, and it only starts to hurt really bad when he is half way in. This was happening when I had chlamydia then during BV, and is still here. But now what could possibly be wrong. My BV is supposed to be cleared up and I'm std free. It happpens every time during sex, one of the worse pains I've ever dealt with and it puts me in tears and I can't have sex. I don't have any other symptoms, just EXTREME burning and pain ONLY when he goes in half way. Once he's in all the way it sometimes stops hurting but most the time it doesn't and that's when I'm in tears. I just don't know what to do anymore I'm always in and out of the doctors..and no it's not vaginal  dryness, something is seriously wrong. It's hurts so bad. 😐
