For me it depends on the situation. I can say that now that I've mellowed some with age. Truth is, I still think it takes a lot of cheek for someone to ask to play my guitar. In a gig situation, I just say no; it's a public place so I don't actually harm them for asking. In a private setting there are people who have played it, though not many. And I never ask anyone to let me play their instruments. I consider it very rude. If they want to hear me play their instruments, they'll ask me.
