What? So you're mad that men has noticed your wife's breasts without a bra under a shirt? And if she was unsure, why would you think she wanted this? No sane woman wants strangers gawking at her and especially at her breasts. I don't think you have to worry about anything.
oh yes darlin she knows those nipples poking out are turning all those men on once she gets bored with that the next thing will be going commando (no panties) and wearing short skirts and not crossing her legs
More likely it's just that she also got sick of the bra, once freed of it she saw the insanity of having to strap herself up all the time in order to not start riots.. when riots didn't happen, the need to prevent them went away.
No. My husband encouraged me to go with no bra. She made her decision and is dealing with the consequences. If you have objections, you should have made them before she made her decision.
Every woman wants to feel beautiful and appreciated. You are a good husband to let her have that and not be jealous or insecure like a weak little boy.
