At what age did you lose your virginity?

Several years back I knew a woman who *loved* having sex with first-timers, especially older ones, guys who were shy, uncomfortable talking with women, or clueless about how to initiate a relationship, but were generally nice guys. She would all but offer herself up to anyone she knew to be a virgin as long as they were nice to her and not repulsive. When I asked her why, she said these men always treated her so well and made her feel important, because she was important to them. She was also amazed at how good they were in bed, perhaps because they'd spent so long just thinking about sex, asking their friends about it, or reading up on it.

I wonder how common this is.
