Basically I'm 16 (a guy), and, while being a bit of a 'late bloomer', I have masturbated, and ejaculted, a fair amount recently. I found it took quite a while, and sometimes I couldn't come. Recently, I've started becoming worse at making myself come while masturbating, so I would welcome any advice on how to do it, as well as info on how long it usually takes a guy to come while masturbating, or whether guys sometimes fail to come etc. Maybe Im just doing it wrong, but either way any advice or info would be great thanks
