NSFW: Why is it so much easier for me to orgasm when I masturbate than it is when I have sex with my boyfriend?

Hi. I’m another jelly. But I’m too embarrassed to ask this question on my real name. Turns out I reveal too much about myself already!

Ok. Important info. When I masturbate, I can generally have an orgasm in 4 or 5 minutes. And if pre-sex I can get a few minutes alone, I can get myself wet and ready pretty fast. Now…my boyfriend turns me on a lot, he’s beautiful and I love him with all of my heart and I want to make love to him constantly. But as soon as he enters the picture it’s like I get distracted. When we’re having sex and I try to bring myself to orgasm, it takes a while. If I get myself close and then he re-enters me, I can get off in a few minutes, but usually it takes more like 10. It’s like I just can’t keep my mind focused.

It’s sort of becoming a problem. I don’t think I used to be like this…I think maybe I’m more inhibited now, if that makes sense, and I can’t just “lose control” like I could before. And I’m only 22! I’ve only been having sex for 4 years! I dont get it…It’s confusing…and I’m looking to solve this problem or at least help it.

Is this common? Help. :( Am I crazy?
