My seventeen year old son punches me in the vagina, is this normal?

The vagina is a hole, and it's impossible to punch someone there when they're in a normal sitting or standing position. Where he's probably punching you is the Mons pubis.
Anyways, no, that's not normal, I suggest you seek counseling for him, as it seems as if he needs some sort of help, as I said, that is not normal.

Why do allow him to hit you there. Give him a good spanking.

nice story. but too sick for a star... sorry.







TROLL!!!!!!!!!!!!!

Troll much?
If this is serious, than no. Your son is a violent freak.

Maybe he's got OCD or ADD or something. That's kind of weird. I wild talk to a doctor or something about that. That doesn't seem too normal. But next time you see his fist coming in for the kill, grab it, twist it, and tell him it's time for you to talk... Lil

he punches it because he thinks if he touches it he'll be known as the person who loves his mom

I'm hoping this is a troll.

But if he really is doing things like that, he needs some serious help.
