First i wanna thank evryone for the info. Its been a SERIOUS help for me lately. But on to my problem....  Ok, this is gonna be a LONG one.
  About 3 months ago i met my dream grl. She is 19, beautiful, smart, sweet, and seXXXy. and she's foreign....
She speaks great english for having only been in the US for a few months, but we're having serious issues in the bedroom.

Prior to her, i've only had sex a few times(3 with the same grl, none of which were enjoyable).  (they were bad btw cause i'd loose my erection and get pissed off and get a HUGE ego burn). Well she and i have had sex 8 times. And its WONDERFUL. Sex with her is wut i always imagined it to be. The passion and the love and the pleasure is all there...the problem is....i told her i've only had sex 3 times before....and she assumes this means that i will ejaculate EXTREMELY quickly.(she has only had one boyfriend in her life and they had sex quite a bit) Well both times i didnt ejac. at all.. She got REALLY mad cause she thinks i lied to her about my past sex life because i "last too long for only 3 times".(when she and i have sex, its usually 20-60 min-foreplay included) What i tried to explain to her is that i masturbated 4 or 5 times a week before she and i began having sex and that im just not as easily stimulated by the soft sides of a vagina yet. I quit masturbating all together after she and i starting hookin up, but it isnt helping. And she still cant understand why i take so long.
On top of all that, she also thinks that she's inadequate cause i havent orgasmd yet.....she cried last time. I feel so bad about it, but i cant seem to explain that sex w/ her feels so great and that i enjoy it even w/o an ejaculation. She says she has "finished"(i.e orgasmd) at least once every time, and twice or more on 2 occasions. and that i havent even done it once. Where she comes from, it is VERY important that women "please" their men in ALL ways. And i Am pleased,but she doesnt believe me because in her mind, the only way to enjoy sex is the end. Im at my wits end tryin to tell her that it is great for me.
The last time we had sex, i lost my erection twice and that also hurt her cause that makes her think i cant feel her when we have sex. It bothers me enough when it flops, but then she gets pissed and the whole process is ruined. I feel like im not enough for her because i cant cum for her and she feels inadequate cause she hasnt been able to get me to do so. she had pretty much decided she doesnt even want to try anymore. I think im in love w/ this grl and it hurts so bad not to be able to make love w/ her that we both enjoy. HELP ME OUT GUYS>

ANY info or suggestions would be great!
