A few things of note:
1) Women are smarter than you think. And craftier than you think. And sneakier than you think.
2) unless you felt her hymen break, you can’t be certain that she was actually a virgin. It’s quite possible she gauged your reaction/beliefs on virginity before she told you what she “was”. She could’ve been plowed more than Route 66 during a snowstorm, but you’d never know it if she didn’t want you to.
With this said... I agree with you here. It’s wrong for her to want a 3some.
You should ask her, “Would you allow a 3some with me, you and another WOMAN?”
I bet you her answer is “no”- lmao!
To that, you should casually and resolutely be like, “Exactly. Now I don’t want to ever hear something like that from you again.”
My husband wanted a 3some with a girl once. I asked if he’d like one with me him and another GUY instead. He got the point, and stopped asking lol.
Keep in mind: It’s always possible your wife could cheat behind your back. Monitor her!
ALSO: usually when a girl asks this, there’s a SPECIFIC guy in mind.
