Re: help...

Some thoughts.

Semen in the urine after ejaculation. This is normal for me, and I've never blinked twice at it. I just consider it normal since there will still be some remaining in the pipe after ejaculation ;). But it depends on the amount I suppose. The previous poster seems to know what he's talking about.

Premature ejaculation. Well who doesn't! If this is of concern and you want to perform better, you probably will have to train yourself. Er, that means learning to recognise when you are going to finish and then back off before you do. This of course will require practice alone. After some time and practice you will be able to recognise and back off(/slow down/take a break) when you need to. Then the same can be applied when you get lucky with a girl.

There are also exercises that you can do to strengthen you pc muscle. That is the muscle that you use to stop urination and also to strengthen an erection to a degree. You can investigate this further on the net.

And by the way, until you find a way around these issues, don't put yourself under pressure. Just relax a bit with the knowledge that premature ejaculation is normal, experienced by all at various times, and can be overcome with a bit of training and practice.
