Since we're now posting personal experiences...
I left home at 16 and not long after met and fell in love with a 20 yr old. We were living together not long after and spent 4 and a half years together. I broke up with him not long before my 21st birthday.
2 - 3 years later, when he was 27 I heard he was going out with a 13 yr old. I was disgusted. A few years back, out of curiosity I googled him. He had been arrested and charged (I can't remember what the exact charges were). I get the impression his parents went broke getting a lawyer because he got 9 months good behaviour and booted out of the state that he was living in.
What's my point? In some cases this can lead to a scary trend. My ex always told me I was too young for him and he would never go out with a younger person again. Yes, he was screwed up, but obviously was attracted to younger people because they are so easy to influence and intimidate. Any grown man chasing a child has a problem.
