Can guys stick to one woman?

With enough Gorilla Glue, anybody can stick to anything.

Guys who care about finding that one special person and who is ready to commit and settle down can stick to one woman. But guys who are not ready for a real relationship can't. or wont, rather.

I can and I just need to convince Shakira and then break the bad news to my wife

if she stops being a bipolar asshole, then yeah

Yeah, for sure if she's a nice person!

Some. Not all.

Sure, if they want to. Many (most?) guys are so invested in their privilege of being Men, they don't

Yup
