The following tags (and variations I'm forgetting) male_penetrating_male, male_penetrating_female, female_penetrating_female, male_penetrating_intersex, intersex_penetrating_male, intersex_penetrating_female, female_penetrating_intersex, etc. should imply the tag sex

I mean people also don't tag those because they think male/female (etc.) is good enough, but a male hugging a female is vastly different than a male fucking a female. square is a rectangle but a rectangle isn't necessarily a square kinda deal, so I understand the lack of auto-association with (gender)/(gender) and penetration, and the fact that sex toys exist that can penetrate. There's like >150 pages of this that I would go through and re-tag manually, but my blacklist blocks a lot of them and honestly I don't have the time.
