Title says it. Simply, it takes me a long time to cum. My main problem used to be that I didn't cum vaginally with my gf, but now I do...most of the time, it just takes a long time. Oral/hand takes forever and I only came once with out helping her out, and that time was with lots of lube and took a while. The main problem now, especially if she gives me oral/hand my penis is actually sore afterward since it takes so much effort to make me cum. And sometimes even after sex. I thought maybe I masturbated too much on my own, but asked around and it seems like I masturbate less than all my friends. My friends said that a guy should cum at least once a day, any "truth" to that. If you count when I masturbate and when I am with my gf its maybe once every 2 days, depending if college is in session or not. Right now its not so I've seen my gf everyday and came 1-3 times nearly every day for about 2 weeks. And the only time I came from just her oral/hand was very recently. So I am going to try and cum at least once a day and see if that makes any difference. Am I just being "stupid" thinking this is a "problem". Because if i am please say so.
