Two things I would like to discuss here,

When I'm fucking a girl with a condom, it's hard to feel anything, I can't even tell if I'm close or sometimes I can't even tell if I already have "crossed the finish line". The only time I could feel it more was when she was on top. I don't plan on not using a condom but I still want to be able to finish and sense how close I am to this.

I've had two instances where after sex my balls ache really bad continuously for about 8 hours after (as if they've been kicked). Is this from going too hard or could it be something else? I only get this issue with sex (mainly missionary).

Thanks guys.
