The title sums it up really; I lost my virginity two weeks ago to my girlfriend... I'm 23 years old by the way. I never really had any problem gaining an erection nor ejaculating beforehand when masturbating. But after returning to London (she's currently living some way out west, in Newfoundland), I find I have very poor sex drive, and my usual (and not so usual) methods of masturbation no longer work, even during normally highly-arousing phonesex. She suffers similarly, except she gets close to climax but cannot quite push over the edge.

Is this a common problem for long-distance lovers who miss eachother? Is it just a mental thing perhaps? I also found I had trouble ejaculating occasionally during sex, regardless of how pleasurable it was (though after a break and switching positions, was usually fine again).

Many thanks in advance for any answers!
