Well, I know that I'm about 7 years late, but if Dan isn't going to cover VT's questions, I guess I will.

1.The average penis is about six inches long erect.

2. This is a trickier question than the other two. If you are just fooling around with a guy and want to all of a sudden have some fun NSA sex, there are going to be problems. I know that I would feel bad about taking a virginity without being told first. If it is someone that you care about however, and he truly cares about you, it should be a pretty special time for him. Of course it's not going to be as fun and raunchy as if it looks in the pornos, but taking a virginity is a pretty special thing. If the guy really cares about you, he will make sure that everything is feeling okay, and that everyone is having a good time.

3.An erection can occur either because a man becomes aroused or just sorta randomly. It's pretty difficult to peg down an average for men in general, but I would guess that it is somewhere around 2-5 times daily (depending on whether or not there is someone/something around to arouse them.
No, it will not hurt a man not to have sex whenever he gets hard, but if he is getting his penis stimulated (by a hand, mouth, vagina, etc.) And it suddenly stops without him getting to finish, he will experience a phenomena commonly referred to as "blue balls". Though his balls will not literally turn blue, they will feel as if they are about to burst (they won't actually) and it will take some time before they start to feel better, unless the job is finished.

I'm not a virgin, Roswell, but I appreciate your willingness to try to answer the questions in good faith for others.

But Dan's answers were much funnier. I presume he suspected VT of being a time-waster.

being a 21 year old virgin myself i would just like to say that its pretty hard to describe just how nervewracking the 'losing it' idea is - at a stage where men look at you and expect you to at least have had one or two sexual partners and be reasonably experienced the idea of actually getting yourself into a situation where having sex is a possibility is really awkward.
what do you say? do?
it honestly puts me of having sex altogether. and im reasonably convinced that if or when i eventually DO have sex itll go to one extreme or the other: a really nice guy ive known for a while in a non-sexual sense eg, a friend who has decided im worth the trouble of awkwardly deflowering me. OR it'll be a really skanky one night stand and i wont even remember the guys name.
I guess its lucky for girs like me that alot of guys have a really perverted obsession with popping cherries. That, and to quote a guy i know "virgins are good because they havent learned bad habits from other dudes"
