I think for my friend and her husband, the biggest benefit of doing it twice, was that it meant neither of them would have to worry about him losing it too soon. Therefore, he would not be embarassed, as it was just expected that he couldn't last long the first time. And she would not be disappointed, and she knew she would get more, right then. I think that over time with more and more practice, this situation got better for them (ie: no need to do it twice) but they eventually divorced so I'm not sure what would have happened in the long run. I do know that she was his first sexual relationship, so they had that in common with you.
Lamby, it would help you a lot to read as much as you can about male sexuality. It helps to defunk the mysteries. I know I was (at one time) so naive and silly about certain preconceived notions that it literally stunted my OWN sexuality! I will ever be grateful to MYSELF for eventually taking the time to do my own study of the subject of male sexuality. It was all part of a study of human behavior I was doing by my own choice, but it branched out into these mysteries. I've changed so much since before that time. I know it will help you, too.
Keep trying what works and quickly abandon what doesn't work, keep reading (no matter how busy, squeeze in a little time for it!) and keep posting when you can.
