Overdue virgins: what do your parents think of your condition?

I was inspired by the "How did your parents find out about you losing your virginity" thread here: http://www.thestudentroom.co.uk/showthread.php?t=1579261

Basically what I'm wondering is what do the parents of people who are overdue virgins (lets define that as people who have had much less/no experience at an age when most people have done it or at least something) think of them and do they even know about your "condition"?

I'm personally 22 and the ultimate virgin: never kissed a girl, never had a gf and still a virgin obviously.

I am not sure if my parents are 100% sure of the extent of my virginity but they've got some clues: when I'm home (though I study in the UK, I'm not from here) I never go out, almost never meet up with friends or anything like that so I'm home constantly so they are well aware of my complete and utter lack of a social life and hence no contact with females. I have always been like this and I never hid anything from my parents: if they asked me something I'd answer it directly.

While at uni we still talk and though its hard for them to know what exactly I do, I think they are vaguely aware of the fact that I don't really go out much.
Sometimes they jokingly ask if I have a girl or not and I answer no and thats about the extent of their inquisitions into my romantic life.
Occasionally my dad has joked about my lack of experience with girls (I don't know if he knows the full picture but he's got an idea) but thats about it, mom never brings the topic up.

What about the rest of you virgins out there?

Solution: TSR orgy.

Thats if you don't mind a dozen cocks and 1 ugly girl in a room, of course.
