Is this normal with sex?

Janna

When my SO and I have sex I have a difficult time getting the sex started. Meaning he is a very big penised guy like, imagine a long dill pickle.. and I'm a small women. So I just assume I become raw after sex but the problem is that I may be wet at first but then it's not as wet during for the entire time. Lately he has been finishing in me, kind of ttc, however it doesn't hurt when he does finish. It's after we both go to the bathroom and wipe up and pee I get so irritated down there. It feels like a little bit of burning but in a raw way( if that makes sense). I can't get comfortable to go to sleep or to even cuddle.. any ideas? We have both been checked recently. So std isn't a issue.
