Only find older men attractive?

I am 19. I hate dated men my age all the way to 15 years old than me. I am starting to find that when I go out with friends I am not pointing out the guys my age as being attractive, I am pointing out guys that are 15 years+. Is it okay? I have always had a stable dad in my life, so its not like i am looking for someone to fill that daddy roll. There is just something about a man with age that I find extremely hot. Even tonight when I took my niece out putt putting the group in front of us was a group of older men. I kept eying down the guy that looked the oldest out of the group maybe about 34. My friends call me crazy, and I know my family would never approve. But I just can't help it. Is it wrong?
