'kay, so I was advised to start a new thread for a separate issue regarding my confusion about tags. So! I've seen images where the actual penetration could not be seen, yet which still got anal_penetration or vaginal_penetration depending on...things. 'cause of this, I was under the impression that when the actual penetration was not plainly visible, one had to use logical reasoning, and/or judge based on the location and angle the penis/sex toy/what-have-you is going in, in order to determine whether it's anal or vaginal. I was also under the impression that if such reasoning could be used to conclude the penetration is probably vaginal, a vagina could be assumed, so that a character with breasts and a penis being taken in a way that's most likely vaginal; could be assumed a herm, rather than gynomorph.

Am I just completely mistaken about all of this, or...what's the deal with that?
