The tag implication #37578 pegging -> female_penetrating_male has been rejected.

Reason: Because pegging is described as:
A female character wearing a strapon and using the sex toy to engage in anal sex with a receiving male character.

EDIT: The tag implication pegging -> female_penetrating_male (forum #304377) has been rejected by @Millcore.

This has already been suggested before: forum topic #26364. Since this is heavily debated, it's worth seeing older arguments.

To play devil's advocate the strap-on is not exclusive to women, but rather anything without a penis including eunuchs or cuntboys.

Yes, but pegging is a specific use of a strap-on by a female on a male anally.

https://en.wikipedia.org/wiki/Pegging_(sexual_practice)#
Pegging is a sexual practice in which a woman performs anal sex on a man by penetrating his anus with a strap-on dildo. This practice may also involve stimulating the male genitalia.

Put simply, pegging is a practice in which a woman anally penetrates a man with a strap-on.

Most often, pegging is used to refer to a hetero, cisgender woman who uses a strap-on dildo to penetrate a hetero, cisgender man.

e621's own wiki says:
A female character wearing a strapon and using the sex toy to engage in anal sex with a receiving male character.

Based on the predominantly negative reaction to topic #26364, pegging should probably be aliased to another tag or at the very least have its wiki changed.

Perhaps some implications should be removed regardless: if it is not female_penetrating_male, then it is not male/female either, since it necessarily involves one character penetrating another.

Community agreement seems to be opposed to the wiki definition, so the latter should be modified to fit e621 purposes.
