Sex is more than just a physical response. Your emotions have something to do with it, too. Sex is supposed to be enjoyable but it's tough to have fun if you're constantly worrying about how well you're doing. When your mind is too stressed out to focus on sex, your body can't get excited either.

Sexual performance anxiety can have various potential causes, including fear of failure, pressure to meet expectations, negative self-image, past sexual experiences, relationship issues, lack of sexual knowledge or confidence, and general anxiety or stress.

It's important to communicate openly with a partner and consider seeking professional help if this anxiety persists.
