average age people are loosing their virginity in America now- ITN?

I dont live in America, but I'm 22 years old and still a virgin. I'm not saving my self for marriage, but I'm not opposed it. And no, I'm not religious. I thought a lot of having sex at 15-16(peer presure) but there was no one that I knew who I wanted to have sex with. Later on I stopped thinking about it, instead it felt special that I had something most people my age had given away. Most people dont believe me when I tell them that I'm a vigin, not just because of my age, but because I'm not unattractive (I have done some modeling) and I do flirt with man. I rather say: I became sexually active in my 20s when I knew myself and what I wanted than to say: I wasen't even legal and I did it because everyone else was doing it.
