With as much evidence as the person responding to, sure. Albeit my sample size isn't the largest (think I've gamed with about 50 people in total from when I was 16 until 30), 45 had active sex lives (talking while we played, not 'years later when they grew up' so this includes teens), and 2 I'm sure will die virgins. Of course one can then move the goal posts and say "but were they hot/rich/asian porn stars*"... but at least the partners weren't paid by the hour :P
So, until they study of 10,000 gamers and percentages of "virgins over 15/18/30" are out, I'd say yeah, it's typical. Eat/breath/sleep gaming, sure - any obsessive becomes less attractive (and indifferent to other pursuits). But kick back Sunday afternoon with a bag of dice and some friends? That isn't stopping your Fridays or Saturdays evenings at all.
*that said two went into porn and one was a stripper for uni money. Pretty sure that part wasn't typical
