However bad the sex is (and believe me, it generally is) I’m not usually looking for redress.
What?
Seconded.
Stay in my birthday suit. I usually just sleep with my undies on, so it’s not like I’m wearing that much less…
Put on PJ’s, have a cig, drink some water, brush teeth, and then back to bed most likely.
This plus a dog who loves to stick his nose in warm, damp, aromatic areas. Also, it either needs to be pjs or cranking the heat up if I don’t want to freeze my ass off.
This is usually the case for me as well; unless I have to worry about people other than my partner seeing me in the nude (houseguests, the outside world, etc.), I stay naked until I have somewhere to go.
Depends. No, not based on time of day. I just like to put on Depends. 
Actually, I always get dressed after. I don’t sleep naked anymore since we had kids and dogs and any “afternoon delight” is just an intermission before we go on with the rest of day so I would need to put clothes on anyway.
The more I read of MeanOldLady’s posts, the more I like her. 
I’m content to lie naked for a while, but once I’ve gotten up to clean up, I’m going to at least put underwear back on. I don’t like to sleep naked, as other guys have mentioned, although I’m not sure I’d ever thought specifically about a fear of testicular torsion. Gah!
Now I want to start a heavy metal rock band called Testicular Torsion.
This is America, folks. You have the right to petition for redress.
It is typically a race between me falling asleep naked and my wife petitioning and being awarded redress in the form of her underwear and a shirt (if they can be found).
I chose “full PJ’s” because it’s winter and I get cold. This answer might change at other times of the year. Thing is, PJ’s are much more comfortable for me to sleep in than panties. Bra? Never. As a friend of mine put it, “You’ve got to let the lady parts breathe!” 
Nightgown. Gotta stay covered in case of kid invasion.
My husband and I are both undie people. We’ll cuddle for a little bit naked, but before long, we’re both putting on our undies. For me, if it’s bedtime, I’ll just throw on a wife beater and panties; he’ll throw on his boxers. We’re big fans of afternoon sex (hey, we’re newlyweds… don’t have to worry about kids crashing the party and we’re still hot for each other), and when we do that, we’ll cuddle for a bit, but then the clothes come back on. When he works double shifts on Saturdays, he’ll usually come home for an hour or two … I like giving him something to think about during the dinner service…
We’ll hop in the shower and clean up, then put on what we usually sleep in. Wife’s a neat freak and I…uh…drool otherwise.
Depends. As I’ve grown older and more dysmorphic, I’ve favored putting on sleeping clothes. Any more, since my current gf is a copious female ejaculator, post-coital showers have moved into the mandatory stage, and putting something on afterwards just seems like the right thing to do.
What sort of unimaginative prude came up with the poll? Not really meant as a slam on the OP (in fact, anyone who comes up with such a poll topic is a pretty likeable sort in my book), but really the time and opportunity and circumstances of sex is so varied for the average person (well, me) that it can’t be quantified.
For example, so far every morning this week, we’ve made love before I head out for work, I would think you can guess what option that entails.
Sometimes, we do it before we go to bed - since I sleep nude that requires another vote. She usually wears PJs, but sometimes puts her underwear back on, sometimes leaves it off (I usually don’t bother removing her top all the way, interferes with the spontenaity of the thing, just move it out of the way enough (unbutton if it’s that kind of shirt) to get at the areas of interest under it).
Sometimes, it may be the middle of the day and the kids are afoot elsewhere.
So, I echo corkboard and kayaker’s thoughts.
Hey, I did that gag already!
