Kind of new to sex... have a couple problems

I'm new to sex and I've been experiencing a couple problems with my girlfriend. I've only ever been with one other girl which was a one night stand and I couldn't perform for her, as in couldn't keep it up, but I thought it was because I was drunk on whiskey and had the dreaded whiskey dick. On the morning after the one night stand I could get it up but it wasn't immediately and I was also afraid of being walked in on as I live with my parents and there is no lock on my door.

I started going out with this new girl and I have no problems at all getting it up, it's almost too easy. She can rub her hand up and down my arm and I get hard, and if she is close enough I even have a bit of precum in my pants. The first time we had sex I lasted MAYBE a minute and I was done. The second time I was so excited I was barely in her before I went off. So I tried going solo before sex to take the edge off and then I couldn't stay hard even after 10 minutes of rest.

What I'm worried about is for the last several years I have looked at a lot of porn, I mean about a half hour per day 5 days a week and I masturbate once a day. I'm worried that I might have what they call "porno creep" where I'm so used to porn that the thought of being with a real woman who cares about me scares me off. But I can get hard and have sex though even though I'm a 2 minute Tommy.

This is bugging me because my GF says she's a very sexual person and actually has a secret sex box under her bed with condoms, lube, a vibrator (which she needs a new one because she burnt out the old one) and a vibrating cock ring. When she told me this I was so turned on and I know she's going to want alot of sex.

At least I can make her cum in other ways, and I consider it my duty to do so. Apparently despite my lack of experience I'm great at oral and hands-on.

Can anyone tell me what's wrong with me? I need to know because I want to make my GF happy. She says because I haven't had alot of sex I lost my stamina and have to get it back. I'm willing to do whatever it takes because this girl is awesome and I want to please her in every way I can. Any help is appreciated.

Thanks!

Firstly, don't worry it's bloody scary the first couple of times! Secondly, the secret to performing in bed comes from understanding a woman's body and knowing how to stimulate it...

If I were you i'd spend some time really reading up on female erogenous zones and then think about how you can satisfy her before having sex... think about it... if you have a problem with stamina, that only affects your penis doesn't it? What about your hands and your tongue? Why not work on those techniques... here's a tip...

Fingering:

1.) Place your fingers palm down so that they are pointing down towards her vagina;
2.) place your longest finger directly above her clitoris. If you don't know where this is, it's simple, where the two flats of her vagina meet at the top you'll feel a small raised bump, that's the clitoris, it's like having your finger between two hills (her Labia);
3.)Once your longest finger is on her clitoris draw it back up slightly, here you should feel (if you press) a short thin band of muscle which connects to directly to the clitoris;
4.) Start rubbing your fingers in a steady motion around this muscle so that just the nip of your finger touches down onto the clitoris at the lowest end of the circle.
5.) While you're doing this use your other arm to hold her against you, kiss her lips, cheeks, neck and nibble on her the lobe of her ear, all the time keeping the rythm with your hand down below (put your finger inside her and wipe the moisture back up over her clitoris and the area you are rubbing;
6.) listen to her breathing and her reactions to your fingers, heavy breathing and her pulling you tight - they're good signs, her squirming - bad sign, move your hand slightly back, you're probably stimulating the clitoris too heavily.
7.) Increase the speed and motion of your hand as she breathes more heavily... keep going and you should be able to bring her to climax...

The point is, if you learn how to make a woman orgasm using your fingers and tongue... they won't mind not orgasming during sex! Concentrate on pleasing her completely before thinking about yourself - this is the part that requires control...

I read this guide when I was younger and although it's another hard sell 'BS' site it actually contains a hell of a lot of information and diagrams on how to perfect your techniques... It's probably worth it, just to get your confidence up!

Anyway, let me know if this is helpful or if you want a better explanation of the above technique...

p.s. in relation to an orgasm during sex, just remember this 'ABC' always be thinking clitoris! The closer your pelvis is grinding with her Pubic bone, the better!!! In every position, think how you can pull her closer to you so that you are grinding against her clitoris!
