Let me clarify that grinding is not the word we are looking for, this is both a penis and a pussy rubbing, not just one rubbing on someone.

So, anyone got some good names?

post #1042959 is the example I'll use, and as you can see, it is tagged grinding. Apon reading the wiki, and of those for tribadism and frottage, I noticed that grinding does not actually mean penis on pussy, while editing the latter two wiki pages to include that act.

I have one suggestion as of now: penis/pussy_rubbing, as follows our male/female and etc. tags, and is preferred (to me) over penis_rubbing_pussy or pussy_rubbing_penis, however those could be two separate tags to tag the seperate actions, as my example would have pussy_rubbing_penis.
