I don't really know about you guys, but 13-year-old-me wouldn't feel "Confused" or "Molested", as probably wouldn't a lot other male kids of that age.
He probably had a good time and let's face it, this will probably improve his social life (altho his parents might go crazy) beyond belief, overall, it's my opinion (just an opinion for those of you rushing to flame me), the kid got lucky, but she should still go to jail, even though in this case (older woman, younger male) this can turn out positive, sometimes it also doesn't, which is why this can't be ever labeled as legal, which is a good thing in the end.
