Open Question: Problem with ejaculation?

[feedcrawler]

i'm a 16 year old guy, who masturbates a bit differently than most males. since i was yovng i always rubbed my penis to my bed or to the floor. i think 'bed humping' is somewhat the most adequate word. but anyhow, problem is i can't ejaculate if i masturbate with my hand like most guys, so i always do the 'bed humping' thing. anyway, yesterday i was out with a girl who gave me a handjob but i could not cum. pretty much cuz im not used to that...i guess. also she gave me a foot job(and i have a foot fetish) but that still didn't work! But we were doing stuff for a whole hour and i guess there was a lot of semen produced in my body and then it started to hurt a lot so i had to go home and masturbate myself to get it out. so my question is..how do i learn how to ejaculate so everytime im with a girl i dont have to run back home after an hour..cuz the feeling you get when there's a lot of sperm in you that just wants to go out ..is just really really painful.
