The honest answer is, “Some are turned off, most aren’t, and a few are turned on by it.” Your guy is probably in the majority.
Even the most hardened player tends to pause when he bumps his nose against a virgin. It is quite a solemn responsibility, being the first. The first time is supposed to be special, tender, all that romantic rubbish. And it is almost invariably unsatisfactory to both parties, unless the guy is incredibly patient and takes it slow and gentle with lots and lots of foreplay.
How many guys like that are there kicking around, available? More than you might think, but the odds are against you still. It usually won’t be until somewhere between the third and tenth time that you actually start enjoying it a lot, as you find out what works best for your body, and what works best for him.
Admitting you are a virgin is nothing to be embarrassed about. Everyone was once. And who knows – your guy may well be one of the patient and careful ones that makes even the first time a joy, and sets an impossibly high standard for any that follow.
