I'm 15 abd this girl is 19 can we date if my parents say its OK

Date, yes. But you are under the age of consent for sex.

And I can't understand what interest a 19 yr old girl would have with a 15 yr old boy. Nor what parents of a 15 yr old boy would permit him to date a 19 yr old girl.

It's also considered pedophilia for someone older than 18 to date someone under 16.

The definition of pedophilia is an adult having a sexual attraction for children. It has nothing to do with dating.

I agree with Scott but the definition is more specific than an adult attraction to a child. I believe a 16 year old having designs on a 13 ywear old would qualify. Still, does not apply to dating.
