I'm still a virgin, but I have noticed when I masturbate whilst watching porn I can go on forever up until the guy penetrates the woman with his cock and she starts moaning then I just have to cum instantly. I was wondering if this means I would be one of those early finishers when it does come to the big day? Anyone else have anything similar? If I am a premature ejaculator, does anyone have any tips or links to any threads here that can help solve my problem??
