Hi, I was just hoping for advice. Im 21M not inexperienced at sex but have very little experience and ive noticed both in my alone time and when I was with my ex, my whole body as well as my dick gets overly sensitive, which to a degree is normal but because its so sensitive I feel like cumming really quickly, and im not sure if its a state of prejac or I just dont know how to make myself last longer.

Ive had sex that has lasted for an hour or so but thats because of the cknstant change of positions, pacing, and sometimes switching to my mouth and hands instead. But I dont get how some people can just pound and pound, or just let the woman too because if I did that, which I would like, I wouldnt last long before asking her to stop, i know it can be normal and maybe im just young and inexperienced but its embarrassinh and deters me from having those relations becuase I dont eant to disappoint.

Any help would be appreciated, thank you.
