Is it normal that a 21 years old girl doesn't know anything about sex?
I really don't know anything about sex.
I'm still a virgin, but I think that I should know some things about sex.
I don't talk about this problem with anyone, because I'm ashamed of my ignorance.
I can say that in a scale from 0 to 10, my knowledge about sex is 0.
And I feel more embarrassed because of my age. I feel so dumb and naive...
