Are all men cheaters?

Am I the only one who wonders if a hot girl were to go up to my man when he’s alone and flirt/ask for his # would he? My man has been faithful but I feel like it’s only because he’s not SUPER HOT where women are always throwing themselves at him. But I wonder if one day when the opportunity arises, would he be so flatter and go for it. I’ve been hit on in public when I’m alone by MANY men that are taken. Although my man isn’t the type to go up to a random woman, what if a woman went up to HIM. Lol I can’t be the only one who has thought of this.
