well it's pretty simple, i just can't seem to come during sex. my girlfriend is the only person i've been with and we've used a condom everytime. i am sexually attracted to her and i can get an erection without a problem and all, but i just can't come. it's gotten on both of our nerves, so i thought i'd come here for help.
suggestions from those more experienced would be appreciated.
i am a male 16 years of age, by the way.
