Re: staying hard and lasting
Actually, I used masturbation to learn how to last longer. I would masturbate to a point where I felt like ejaculation was about to happen and then stop. I'd then start up again. In doing so, I learned the muscles involved in getting to the point of ejaculation and how to control them. Now, I can last as long as I want and ejaculate almost on demand. I would also watch porn to get into different techniques, positions and fantasies. I'd make sure that I could last through several "scenes". As for staying hard, try to enjoy what you're doing and feeling and spend considerable more thoght into what she is feeling. Try to read her movements to know what makes her feel better. If you need to fall into a little mental fantasy, then go ahead. But usually spending your mental time trying to please her takes care of both problems.
