Is this feeling normal?

K

Sometimes when my boyfriend and I have sex it feels like pokey when he’s in me. It doesn’t hurt just feels like it’s pokey? Is this normal? What could this possibly be from? I have no pain at all down there in general either. I also don’t use the IUD as a form of birth control btw, I have the implant. So this feeling isn’t from birth control. Just confused and not sure if this feeling is normal or not.
