Carpet Burn

I need help with a situation that occurs when my boyfriend and I have sex. During its fine. There's no irritation and I'm properly lubed and everything. But afterwards there is this god awful burning, mostly on my clit. Peeing is excruciating. I know it's not a UTI because I've gotten that before and it's not the same feeling. It almost feels like carpet burn. Could it be because he does not manscape and it rubs me?
