I feel like I never finish..

So let me just say it... I feel like I can never follow through with my orgasms. I have a few times when I first started having sex. I’ve had different sexual partners and has always had this same problem... and it’s NOT the guys’ sex game. I enjoy sex/foreplay and everything about it. But when I feel that I’m going to “cum” It never comes! And when it won’t happen naturally I start to overthink about it (during the sex) trying to force it out, which doesn’t help at all.

What’s wrong with me? Is there something wrong? .... is it just me?

How can fix this lol I feel like I’m cheating myself out of the full experience sometimes
