A sex related ethical dilemma.... lol ten points to best!?

I'm 16. I like older men. mid-20s to mid-40s is about the range. I confessed this to my guy friend (who is my age) and he said it was the weirdest/most disgusting thing he's ever heard. And I'm just wondering... is it? I mean, it's never wrong to love, right? But why would my friend say this? Is wanting older men (yes, sexually. grow up lol) wrong?
