These kinds of combo tags bloat the tag list.
And [gender]_[verb]_[form] is rather confusing. It's unclear from the tag name if you can use it when both characters are the same form or the same sex.
A similar tag [gender]_penetrating_[form]'s wiki says you can't use it on the same forms. Still, male_penetrating_feral feral_on_feral has 721 posts. That means about 13% of male_penetrating_feral is a mistag.
The former discussion (topic #60466) also mentions that while x_penetrating_y is a special case, other verb combos should be aliased away.
