Both my gf and I just lost our virginities to each other and have been just doing foreplay before. When we first began to do stuff, we both wouldn’t finish, but eventually she figured out what I like and can make me finish pretty quick. I’ve tried but I don’t make her finish often. There was one time that I made her orgasm from fingering twice in like 20 minutes, but even when I try doing the same thing, she says it starts hurting after too long. She says that she thinks the reason she doesn’t finish is that she gets too in her head, that it’s not my fault, and that she still enjoys it. It still sucks that I can’t make her finish. What can we do? How can I help her stop overthinking?
