I'm a 16 year old boy who has just started exploring with my gf. I always had a slight case of phimosis, which didn't bother me so much. I have no problem retracting my foreskin when not erect, but in an erection it would always hurt so i didn't even try retracting it all the way. A couple days ago, i was getting my first blowjob, and i just let her do it her way. When she started pulling my foreskin up and down, first few pulls it was raining pain (but i liked it somehow) and after a minute i got used to it. I think that she kinda solved my phimosis problem since it doesn't hurt nearly as much when pulling itall over, but i have one other problem which conserns me more. My foreskin isn't the same length on both sides, it is slightly longer on the left side and what i realised is that when i retract my foreskin it sometimes gets stuck under the glans but i can easily get it back even tho it folds (so i have to pull it out which hurts a little when not lubricated). I can pull my left side of the foreskin more than the right side so it folds perfectly, but in an erection, since my foreskin is a little tight, i have to aim for that ballance so it folds right. Also, i noticed that when folded the "wrong way" my frenulum slips to the side also. Only thing that i am concerned about is if i can get paraphimosis. If it gets stuck that way, and stays like that for too long during intercourse, can it swell, and when is it the time to fold my foreskin back manually before it is too late?

I'm going to sleep with her in 6 days and we are going to have sex. I'm considering about putting a condom over the foreskin, because i am a little scared of that paraphimosis. What are your thoughts?
