Let me tell you about Wisconsin: We regularly bump 17-year-old offenders into adult court. So, yes, we have had cases of 17-year-old couples tried as adults for having sex with a minor after they had sex with each other.
If the implication of that fact hasn’t sunk in I’ll make it explicit: We treat them as adults for the purposes of being a criminal, and a minor for the purposes of being a victim.
Sheeeeit, don’t hit a guy with those turgid vacuoles without a NSFW tag.
