I stimulate myself a lot

I'll answer the first part of your post SuperBig.

There are NO health problems with masturbation.  You can do it as often as you want.  It is BENEFICIAL to your prostate health.

But: if you masturbate just to ejaculate quickly, you're probably setting yourself up for premature ejaculation.

Use your masturbation sessions to learn control.  Make them last.  You can easily make it last or an hour or more if you try.  Focus on those feelings just before you ejaculate and try to get just about to that point without ejaculating.  The longer you keep at that point, called "edging" the better your orgasm.

Good luck.

thanks for the first part of my struggle your adviadvice shal be out to the test. but I guess the second part of my problem will come at its own time as a girl :) I hope

TAKE YOUR TIME AND DISCOVER YOURSELF FIRST. WHEN IT IS TIME FOR A GIRL THINGS WILL COME NATURALLY, BUT AT LEAST YOU';; KNOW WHAT TO EXPECT
