It's common to wonder about sexual performance, particularly if you've been engaging in masturbation quite often. Fast termination during sexual intercourse is called premature ejaculation (PE). The symptoms of PE are being unable to command when you ejaculate. Too much masturbation can be a reason for PE. Reduce the frequency of masturbation- practice methods of delaying ejaculation like the start-stop method, and- communicate honestly about your worries despite finding this advice difficult.
