Hm. Oddly formed question..

Well anyhow, warm greetings. I'm somewhat old to this threadboards but just recently decided to register and join. As if I knew I'll have a question to ask. I'm looking forward on helping out with my own knowledge. You may just call me Tormentor. Now...let me present you a problem.

I'm somewhat experienced with sex and I'm pretty good in performing and use of the decently solid knowledge I posses. As a matter of a fact rumor has it I know how a woman works, but still at the same time I'm having difficulties with myself, what sucks. My girlfriend and I are together for about two years now and I'm managing to release her from her asexuality and brainlock just recent months (She had bad experiences and is generally very shy when speaking of sexuality so it was really hard reaching this level of intimacy). During our first sex I was practically able of constant penetration for at least five hours (was a common thing for me), but as we were short in time and all I completed the task in 2 but I had several moments when I thought I'll cum before she does, and that IS NOT something I do. Another thing is - it takes really, really long for her to cum and I need to master myself. I know why it took me a longer but shorter time, but let us proceed:

However, during our second,third time I had a lot of problems. I cummed almost in half an hour, and then had to slow down and stop and stop again and again and it was a god damn torment (:P) and eventually I couldn't even control it anymore and cummed in an hour or so, before her, and had to stimulate her further with my tongue so that she could cum. >_>

You see, the problem is in "her-me". I'm extremly aroused by her. I can get "horny" in a matter of ten-twenty seconds when I just think of her. Just think, like, for example, where are we going out tonight. During sex, her body gets a sensual, specific bronze-warm color, I'm naturally very attracted by sweating body, her cheeks fill with blood, she lightly opens her mouth and she has beautiful, natural moans and gasps I'm brutally attracted to. Also, when she really enjoys it, she stars moving as well, wildly, and I react to that too, and I'm her first, she is tight, and generally has an extremly pretty vagina (and since I love erotic art and find womans body poetic, I'm additcted to inner and outer of female genitalia), AND, on the very top of all this, while penetrating her, or better, rubbing her vaginal cannal I sense very different currents I simply love. She, as such, is a source of massive stimulation to my psychic and I am having extremly hard time controling something I was before able to play with as I wanted. With her, not even my common tricks like thinking on something stupid, wandering away, pulling out jokes or stopping for ten seconds helps.

This is very, very depressing. I want and live for pleasuring woman first, and then doing whatever I want with myself if I want. I usually use double-durex perfoma condoms, which really help but she really enjoys the sex when I put durex arouser (ribs, lubricant), and I even think it's the arouser that makes me cum so quickly, and if she likes the arouser, I need something to prevent arouser on myself. I tried with perfoma being beneath the arouser but it didn't prevent the stimulation on the top.

What I'm asking is - do you know any ways, or have links linking to sites with such information, with which I can slow down my cumming (without some special tools or stuff, that's plain ineffective). I really need to master myself and extend the time, or better - beat my psych with physicalities beacuse I can't control in front of her. Any advice is welcome, some slowing down techniques, change of tempo, firm pressure on dick, some angles, or other things, anything at all.
