Dysfunction? HELP OUT

[srtitout]

Hi there, I was hoping the guys out there could help me out with this one. I am a 20 year old male and lost my virginity when I was 19, to some random chick at a party. Since then, I have had sex multiple times, with multiple partners (I used to be very shy before university). The only problem is that I have never orgasmed with a girl. No matter what she is doing, or who it is, i've never been able to reach it. Now, Ive been thinking it could be one of 3 problems: My first time, we did it without a condom, and I was scared to let go... 2nd, I really over think things- when I have sex I think about how she is feeling, etc and if I start to worry about keeping it up, it goes soft (bad eh). Finally, maybe its the way I masturbate- I use a pretty tight grip with my right hand, never had anything different. I can orgasm every time I masturbate. Im hoping other people out there have this problem, and maybe someone can offer advice? Thanks a lot

I'll be honest, I know a lot of people who prefer to bang with out the dome so maybe that's it. I'm not saying you should follow suit but you understand my point. Try not to think too much either, when you're bangin. That will mitigate the strength of your hard on. Trust me, I know from experience. Lastly, I would try to keep jerkin off to  an absolute  minimum. You will become too used to the sensation of your hand. Trust me on this one too, I know from experience and it is annoying as all hell when your with a fine girl, and you can't keep it up.

You are able to attain a strong erection and reach orgasm when you masturbate, so I'm sure there's nothing wrong with you. Everyone's different, I guess. In my case, I usually can't reach orgasm when I'm penetrating but I don't see it as a problem.
