The title says it all. When I penetrate my girlfriend, the sex is very good. She feels pleasured, I feel sexually satisfied, but it feels like I’m fucking a tub of vinegar. It’s not that she’s not sexually excited because she’s extremely wet and actually makes a mess on the bedsheet (I have to change them every time). It just feels like I’m fucking a bottle of vinegar and I don’t know why. It still pleasurable(she cums and I cum), but my penis definitely burns after sex (and during) and I find myself washing after to prevent burning of my genitals. She’s on birth control so I don’t wear a condom.

Has anyone experienced this? I’d like a solution to fix this as it does hurt a bit.

I haven’t mentioned this to her as I don’t want to hurt her feelings because I love her very much. Please help.

Is my penis just sensitive? Please help and thank you in advance!
