[NSFW] Specific masturbation tags

In searching for unrelated things, I learned that e621 has specific masturbation tags for specific genital stimulation.
 
To make that clear, this image would be tagged penile masturbation there.
 

 
But there is no equivalent tag for that, or the equivalent vaginal masturbation here.
 
There are already variations of masturbation tags with sex toys going up specific holes, but none for hoof/hand touching those specific holes or rods.
 
Would penile masturbation, vaginal masturbation, clitoral masturbation (and maybe anal masturbation?) be useful tags to have here?

anal one maybe, the others would be useful, but not as much considering penile/vaginal generally is easily found by just searching solo female/male, masturbation. Perhaps they could have some use for futa pics since they have both options.
 
Clitoral vs vaginal I doubt seeing much usage for clitoral.
 
tl;dr
 
usefulness list imo anal>vaginal/penile>clitoral.
 
However even at that, in most cases it’s solved with anal/vaginal insertion or solo female/male + masturbation

I would think masturbation + a specific genital tag would usually work. Most masturbation pictures are solo ones anyway, unless we’re talking about mutual masturbation or something voyeuristic.
 
Granted it does have it’s uses, such as in the aforementioned exceptions. I guess there is a place for it, if you’re willing to put in the effort.

By the way, should masturbation using own hooves be tagged hoofjob? Or is it just for sb doing it with someone else?

@Crusier  
I don’t think so. It’s the pony version of a handjob. You don’t give yourself handjobs.

Then how it should be tagged? Because if handjobs are being tagged, then why not “auto handjobs” ?

@Crusier  
Because that’s what masturbation is for, right ?

@Lead Pie  
OK, I missed the point of this thread. The proposed tags are just for that. But they names are not really self explanatory.
 
penile masturbation, vaginal masturbation, clitoral masturbation, anal masturbation don’t really point that somebody touches oneself with hands/hooves.
 
It would be better to maybe just us the tags we use for sex (fisting, fingring, handjob) but add “auto” as a prefix. Just like we have “facial” and “autofacial”, “fellatio” and “autofellatio”.

@Crusier  
But they do, if you masturbate you touch yourself. How else should you do it ?  
Okay, toys. But there’s also the insertion tag and stuff.

You don’t have to insert toys

I agree wholeheartedly with adding these tags, by the way. Not all the images can be found with a search for solo,masturbation, as masturbation is not at all exclusive to solo images.

@byte[]  
No, but generally x insertion, masturbation will do it for anal/vaginal(/oral(?))
 
Jerking off is a bit harder, but yeah.
