I have a small ********?

Seriously,I need advice on this. I am 24 years old w/one child. All the guys I had with even my current boyfriend said my woo-hoo is very tight. I thought it was talk at first, but one night my bf had a hard time getting in so much it hurt him & me. He loves it , because he says it's like having w/a virgin. However,I 'm in pain. I went to the OBGYN & he said everything is fine. Should I be concerned?
