As I said Lisa, you are going to find as many answers as there are people out there.
Just imagine anything in your head, and there will be someone who thinks that.
Rather than worry why someone else does something you have no control over, maybe you need to examine why it's so important to you.
I'm confident the reasons men do this are exactly the same as women. Especially since they are such simple and predictable creatures.
If you're going to pretend like you looking for some meaningful answer, you wouldn't have called called your audience simple and predictable.
I'd imagine most intelligent men would be insulted enough by that they wouldn't answer.
Plus, most of the men here beyond the age where this stuff means anything.
That leaves the one's you really don't care about to answer.
