is it ok for a husband to let his wife have sex with other men when she wants to
Hi Neil,
It's you and your wife's decision.
Just remember, the more sexual partners the increased risk of sexually transmitted infections including HIV. You are basically having sex with anyone that has had sex with her other partners.
You can't tell by appearances if someone has ANY STD. Some don't show symptoms.
Also consider what would happen if there was a pregnancy?
