Sexist Observation: What's with some guys and their guitars?

The guys I tend to know are the kind of guys who shouldn't be allowed near a microphone or a guitar. That's what I get for doing improv comedy and stuff. I mean, I love these guys. Bless them, but sheesh! Dare I compare them to my nephew, who as an innocent toddler, couldn't keep his hands out of his shorts? His mother would gently pipe, "Don't worry, it's still there!" What's endearing and natural in preschool is a bit sad in latter life. Am I being mean here, or what?
