okay... so i've been with the same girl for a year and a half, and i'm completely in love with her... honestly, i know that i'm done and i'm going to marry this girl... so i don't really care much about the sex (not that i don't LOVE having sex with her)... because our relationship is much more than that... but i feel bad because she feels like she isn't pleasuring me enough because i never ever cum... though she always orgasms, i never cum with sex or oral or handjobs... when i masturbate, i can sometime get myself to cum... but it's always lot of work... this has been a problem since i was old enough to really take notice... but i've never felt motivated to do anything about it until now... i want to cum for her more than me... and i'm also looking down the line: what about when we want to have kids? i know that there are lots of options... but the best would be if i could just cum inside of her... i kind of feel like my penis may not be as physically sensitive as it should be??? i've made an appointment to see a urologist, but i'm a bit nervous... is this the kind of thing i should see a urologist about??? is there anything that can be done with this problem? i know that the most obvious answer is to point to a psychological issue, but i don't believe that's it... anyone ever heard of this / experienced it? i've heard of it in women, but not men... any thoughts will be greatly appreciated. thanks.
