What would you do if your husband always likes to send explicit messages to others?

Depends on who the other person is. If you know each other in reality, you must stop it. This is obviously out of line. You want to cheat.

If you are a stranger on the internet, it may be that your husband likes literary love, his sexual fantasies are not satisfied, and he doesn't want to really cheat. To vent it in such a safe way, we must try our best to improve the quality of life of husband and wife. Men don't want to go out fooling around when they are full.
