To me, there are two separate groups that are technically teens: underage (13-17) and adults (18-19). I'm not at all interested in kiddie porn, and I don't go out of my way to locate "teen" porn, because I'm not excited about the concept of innocence or virginity or youth. But the porn that I enjoy sometimes involves women with slender, firm-looking bodies, and they are likely to range in age from 18 to early 20s in age. But a woman could be older than that and very physically fit and I would find that just as appealing. Some so-called "teen" porn features women who look like they are closer in age to 30, but dressed up in teen-looking clothes, and that doesn't generally interest me either, because it's still an innocent virgin-type fantasy, and that's just not interesting to me.
