Hello, i (28m) have been with my gf (28f) for a few months. I have a lit of trauma around sex but things have been great with her and have been having sex for 3months. When we have sex it was usually 30min to an hour long which i enjoyed, but lately i've been cumming a lot faster to the point i only last 5 to 10min.
It's been bothering me as i and her like longer sex but idk why all of tye sudden i'm cumming quicker when nothings changed.
EDIT: sorry to edit so quick but i feel it's important to mention that i enjoy the longer sex because she can orgasm from penetration alone and when we go for an hour i can make her orgasm 3 times or more which i like to do because i like making her feel amazing too.
