I would question the term "sex". Sorry that sounds so Clintonesque, but I would agree that he did not have sex with that woman, Ms. Lewinsky. I would think that sex with an 8-year-old is impossible, given that I think sex is for the purpose of procreation. Maybe what is in view here is merely genital stimulation between individuals.
When discussing laws, simply stating personal opinion is hardly productive. Sadly, society sees sex as our new national pastime to be shared with and between all.
