I guess, when I was 13 I wanted 'something' for sure--I wasn't really sure just what, to be honest. A grown women yanking my pants off would have been weird--I was still very much a child. Maybe I was just way behind the curve--or maybe..I was a completely normal 13 year old totally unready for adult behaviors~As inappropriate as it might be, a 13 year old boy with an erection wants sex.
Me...I'd terminate her parental rights in a heartbeat and allow the victim's family to find redemption and closure in raising their grandchild.
