I know this can be a sensitive topic for males here on PPD but according to TXC most adult women started experiencing creeping by adult males by the time they were 11-14.

There are actually several posts about this.

We also have posts of men who are fathers of teenage daughters and then creep on their friends.

A direct copy of one of those replies a men made.

Some of my daughter's friends are really hot,

I'm the father of a very attractive 15 yr daughter. I can tell you that I in no way think of her in that way .... I do find her friends sexually attractive,

In reply to a man finding his daughters friends attractive another man replied.

Thanks for the honesty. I've always felt alone in my thoughts on the matter.

I personally am disgusted at the amount of men who are OK with this. I'm lucky in that nothing horrible has happened to me, but that's only because I live in a safe country.
