Hello all, I am 17 years old and have had my good share of sexual experience for my age but i have always had a problem with cuming. Now, I've read a few pieces of advice about relaxing while having sex and I assure you, I am very comfortable having sex with my girlfriend as it is or so I think. I'm not exactly sure what's wrong with me, but I've only cum twice with her, once during a blowjob and once while she was on top (if this holds any significance). I know I'm not gay, that's for sure. I love having sex with her, it's the best I've had.

We've switched positions, blowjobs, handjobs, are trying fetishes, I've looked up advice and "relaxed" I think (not too sure about this if anyone wants to go in depth more), and I believe it's beginning to affect her confidence because she's cuming before I do and she really wants me to reduce my endurance (or so we think that is the problem). Is there any way to do this? I've felt like I'm going to cum MULTIPLE times, and the feeling shortly goes away unless she's on top.

I'd appreciate any help. I feel like I'm the only one who's had this problem cause I can't seem to find a topic perfectly regarding my situation.

Thanks in advance!
