Why would you limit it? Isn't he a responsible adult, capable of making adult decisions. The way you put it, you obviously think he's a piece of property you get to boss around and keep on a tight leash. Sad. You're married to a gelding.
I have NO respect for women who put their men on an "allowance" and the same for men who do the same to women.
No sir he’s not gelded,galded some times on hot days but thats not a topic we need to discuss.
I’ll ask him later if he would like more money or less sex that way it can be his decision and he can feel more manly.
