NSFW aftersex vs afterglow vs aftermath

It seems at least aftersex and afterglow are usually used for after sex situations, should they be aliased?
 
Aftermath is sometimes used for non sexual things too, so maybe not that one?

To the best of my knowledge “aftersex” is meant for images shortly after ejaculation with a focus on the juices, while “afterglow” is meant for images shortly after orgasm with a focus on characters’ expressions; I wouldn’t alias these two.
 
No idea what aftermath is for, but I’m guessing the most common use is similar to that of “aftersex”.

@The Smiling Pony  
Could you put that into the descriptions of the tags, so the difference is more clear on when to use them? :)

They seem like they cover something different, so I’d leave them as is. probably some cleanup needed. Specially on Aftermath.
 
Not sure what to put for the description on that one.

I need a mate please

My understanding of “aftersex” is that it’s for like two characters in bed later that night or the morning after, which is probably the same as “aftermath”, although I would caution using a very broad word for such a specific meaning (“aftermath” could be “what happened after I ate taco bell” just as well as “what happened after Sunset and Flash got drunk in Twilight’s bed”… and the fun part is that second one may not even be sex).
 
I would keep afterglow separate from both, it’s a very specific thing immediately post-orgasm. Tag descriptions may help as long as there’s some agreement.

My understanding would be pretty similar  
Afterglow = right after orgasm  
Aftersex = ANY point after sex but still together in the spot where the sex happened
 
Aftermath = consequences of something - maybe this should specifically say “NOT for after sex situations, use the tag aftersex for that” to avoid the ambiguity?

Any more thoughts on that?
