18M, had sex(kinda) for the first time yesterday, need some help

So me and my gf decided to have sex on her 20th bday, it was both of ours first time, I've been in this sub for sometime so I know the first time wasn't gonna be great as such, while putting on the condom, my foreskin hurt too much, so we couldn't have penetration, even while she was giving me a hj, although it felt good, idt I was moving close to a climax, like it happens with my hand. At times, while she was giving hj, my foreskin was being pulled tightly and causing pain.

Here's where we decided to stick to oral, and it was fine ig, her bjs made me feel out of this world, while she came twice during oral. I tried fingering as well and made her cum, but the problem again was, her pussy was literally too tight for 2 fingers, while fingering her with my middle finger, it had minute wiggle room to rotate a bit, but 2 fingers were literally impossible to enter, and my dick is thicker than that, so even without the foreskin issue, penetration seemed impossible.

So ITS, please tell me what would the solution of this be? as my birthday is coming soon (wink)
