Hey everyone.
I am new to sex and had a question about balls.
Is it normal for your balls to go into the vagina with your penis?
I am of average length I think, but maybe a bit on the thin side. When I have sex with my girlfriend, my balls go all the way into her vagina. She says this has never happened before and I'm worried that I'm maybe going in to deep.
Usually before sex, she likes me to finger her with my entire hand. Kinda like a fist. Then I just kinda like, uppercut it. Maybe I'm hurting it?
Any advice is really appreciated!
