Hey everyone. I'm really worried that i'm gonna blow my load way too fast when im with my gf and we finally have sex or she decides to give me a blowjob. They say worrying about it makes it even worse, but I cant help it! Ive heard that kegals can help you last longer however ive also heard in these forums that people have been hurt from it. Can someone please tell me if they actually do work and if they do cause harm? Also whats a 'pc muscle'?

Thanks everyone :)
