> When I recieve oral sex or a hand job I am fine but during sex I just don't feel anything when I thrust in or out.

Are you wearing a condom? If so, the insulation provided by the condom lining will reduce the sensations.

> every time it seems boring as I don't feel much when I'm doing it. Even after about 20 minutes. I have never 'finished' during sex.

Sounds like you are placing the cart before the horse. We've recently been inundated by statements like this from newbys who believe incorrectly that stroking and thrusting are the means to the end. NOT SO. Stroking maintains the existing high level of arousal; thrusting peaks this and triggers the climax.

Intercourse that goes on for longer than ten minutes is not good. Women complain about becoming tired, bored and sore.

Arousal is started by an idea, randy thought, and/or some kissing and hugging. Arousal, sexual tension, and, anticipation are build by devoting no less than half an hour, and much more if time permits, to kissing and caressing--and eventually foreplay. Doing this places the horse in its rightful postion before the cart. Your orgasm will take care of itself.

> I have never 'finished' during sex.

If you are furiously humpin' away, then no wonder. Get to the peak of your arousal where you are at the brink of a climax by making out and making out some more. If you begin intercourse at the brink of your orgasm, intercourse will trigger the orgasm.

My guy and I always wait till the very last second to really rip each others clothes off. Grinding through clothes with your girl on top might get you off quite well. Try it with her on top and tell her if your having problems feeling anything.
