This whole situation came to have a new light after the first time I had sex (thankfully, my girlfriend was quite comprehensive)- which was three days ago.
Allow me to elaborate the situation.

Simply put, with no record of any erection problems, and having played the make-out and foreplay rules nicely, I saw things going along reasonable nicely.
Until the vaginal intercourse actually began, and I had the premature ejaculation of a lifetime, lasting less than half a minute.

It didn't concern me much, given my whole novelty, so I browsed this site for further information. My problem is another. Simply put, I seem to be unable to achieve orgasm through masturbation.

I never had many orgasms through masturbation before, but I never gave it much importance. In fact, watching my stash of more adult material and minimal stimulation gave more than a couple of minutes of a raging erection, so I figured it would be alright. The issue here has to do with the 'Start and Stop' exercises intended to improve that premature ejaculation condition, which are pretty much damned in the absence of my partner.

I just wondered if there is supposed to be any particular reason for this, seeing as I have orgasmed through other means before. And if I am the only man with this peculiar problem. It twarts part of the possibilities to deal with the aforementioned unpleasent situation, which saddens me, since I am genuinely in love with the girl.

I am also new to the forums, I hope I am not doing to much harm.
