Balls hurt

Hey there! I don't really know where to post this so I'll just leave it here for now. I have almost 40 days of hard reboot. Things started going great for me since I stopped fapping. I became less anxious, more sociable, started my first year in uni and I found this girl in here, we started gently, evolved with hugs, cuddles but no kisses or sex yet(I'm a 19yo Virgin) and my problem is the following: every time we cuddle my dick wakes up and it's like really hard and ready for action but there is no action and after the cuddling my balls and the whole area down there starts hurting. I guess it's because of semen building up in there and not getting released. Have you experienced things like this one? Is it normal? I don't want to break my soon to be 40 days record of nofap so releasing the semen isn't an option. I had a wet dream back in day 23 but it was the only release I can remember in the last ~40 days
