I've seen several images involving characters with a pseudo-penis being penetrated/fingered/etc. get tagged as sometimes urethral_*, sometimes vaginal_* and sometimes neither of those. I think we should agree on one or the other and change the wiki page to make it clear which of the two should be used.

Going by the site's policy of TWYS, I'd be tempted to say that urethral should have priority, especially since female spotted hyenas (which are pretty much the only reference we have) don't have a separate opening for the vagina, they only have one hole down there and essentially give birth through their urethra.

With that said, I'd understand if people thought otherwise and would rather we use vaginal instead, so I'm asking which of the two seems most logical to people here (at least, those of us who aren't too weirded out to care).
