It really depends.

Most of the time, naked, and if I wear underwear it has a habit of coming off overnight.

Sometimes, usually if it's really humid, "it" will sweat and stick and become uncomfortable (sorry, was that TMI ) in which case I find it better to wear some briefs* to keep everything in a comfortable and manageable bundle.

Or if it's the middle of winter, I'll wear pyjamas because we're in a crappy old house without central heating and it's freezing otherwise.

But most of the time, you can't beat being nekkid.


* Yes I did say briefs. But boxers for the waking life. Use the correct tools for the job!
