Don't know if this will help (not inside a coffin), but a few more (non-MTS2) upright skeletons--

These?

Know there were some solid links to such items here (but don't click on the link - see below):

www.insimenator.org/index.php?topic=102592.0

but for the life of me, can't remember them just now.

The WCIF board currently doesn't go back that far, so clicking that link will not take you there. Don't know if (maybe?) the mods have access to older archives of the WCIF board and might be able to reconstruct that thread/post?

Not quite identical, but some similar ones here:

Particularly the 3rd and 4th choices under Male hair.

I'm terrible at identifying hairs, but the one in the pic looks like it might be from rosesims.

In a case such as that, you could always use the Insimeator's Wardrobe Adjustor, which allows you to change the clothing status of any Sim on the lot (or of every Sim on the lot):

.

Several to choose from at Chinafan Sims:

But you'll have to go through all the 'skins' pages to root them out.

Presumably you're talking about only when woo hoo is performed in bed.

Don't know of anything like that (or if it possible in such a global mod to differentiate between woo hoo locales), but if walking to a dresser or wardrobe to get dressed is too much effort, there is always the pile o' cloithes dresser, which can be placed on a bedroom endtable (or on a desk or on the floor or even on a shelf above the endtable, for example):

Some outfits for various ages:

Several possibilties off the top o' the noggin:

And, while linking to only one page in the specials section there:

http://parsimonious.org/events/6/40.shtml

there are also a variety of similar outfits scattered throughout the 30+ pages of the male clothing area at Parsimonious:

http://parsimonious.org/fashion2/casual/male_1.shtml

And a nifty woodland elvish outfit is included with this Sim:

.

Nothing of which I'm aware which prompts you to assign a preference, but it can be assigned (at varying levels of intensity) using a variety of mods, included among those Insimenator or Sim Blender or ACR or also this hacked object:

See (or better yet, download and print out) Wolfgeek's handy chart -- message #10, here:

Make absolutely sure the lot is unoccupied before changing the zoning and then saving the change when exiting the lot.

Just in case your particular game configuration/computer set-up doesn't accept all lower case cheats (whether or not that is so varies), use:

changeLotZoning community

and then press the Enter key on your keyboard to initiate the cheat.

Just a random thought--

There are nude (and nudist) 'clothes' out there. Why not dress them in those type of outfits?

No links to adult content allowed here, though.
