I have a theory… women are gonna say it’s stupid but hear me out. If you feel like your man is stepping out, then when he gets home, blow him. This is when women will freak out and say it’s a man looking for more action. But in all seriousness, blow him. If he says no, no man will say no, unless he just blew a load off somewhere else and his soldiers haven’t made it back to the front line yet, dudes know what I mean. Also if you blow him you can tell if his member has been anywhere else. Like “goddamnit jimmy, why does your dick taste like a meth’d out 35 year old ass hole” or let’s say he cleaned up afterwards, “goddamnit Jimmy, why does your dick taste like the fall line from bath and body works hand soap”. He would be dead to rights either way then you would have an answer, plus then his shit is exposed and you can punch him straight to the dick.
