I'll discuss the genitals separately, since they have different purposes and a completely different set of tags.

Note that I will be using "male" and "female" as general biological terms, and will be ignoring intersex. This is only to simplify discussion (and to avoid excessive use of quotes).

Male genitals (copulatory organ)

Penis

• Short
• Common in everyday language despite being the "non-slang" term for it
• Limited confusion (a glans is still considered a penis, a sheath is generally not [except for our own tagging])
• Works with most if not all penis-related tags
• penile_* tags have been gaining traction lately

Cock/dick

• More/less the same as penis
• Slang
• (cock) Has slight, but probably insignificant potential for confusion with roosters (cock would be aliased here anyways, so it's kind of a moot point)
• (dick) Is a name, but I doubt anyone would be confused by this

Male gonads

Balls

• Short
• Slang
• Generally works for most ball-related tags
• Complicated by castration and inside_balls
• Some tagging confusion with other kinds of balls (basketball, billiard balls, etc.)

Scrotum and testes/testicles

• Medical terms that, in common language, tend to be used interchangeably to refer to "the balls" (more testes/testicles than scrotum)
• Scrotum is the sac (analogous to "female" vulva) whereas testes/testicles are the actual gonads inside the scrotum
• You can have a scrotum without testes/testicles and you can have testes without balls
• Neither of these terms really help with reducing confusion with tagging over the shorter "balls"
• Complicated by castration and inside_balls

Female genitals

Pussy

• Short
• Slang
• Works to refer to the external and internal area (though we mostly tag external)
• Minor confusion with cats (pussy would be aliased to the main tag if it were changed anyways, so it's kind of a moot point)
• Minor confusion with wimp/pansy/feminine male (unlikely)
• pussy_penetration may work to replace vaginal_* (even if it's a bit awkward), but there's nothing to replace vaginal itself

Cunt

• Mostly the same as pussy
• Some people find it extremely derogatory
• That's pretty much all I have to say about this one :/

Vagina

• Refers informally to both the area as a whole, and the inside part of the hole itself wordplay intended
• Works well with the vaginal_* tags
• vaginal_juice and vaginal_ejaculation are a bit awkward sounding, but might work well enough

Vulva/labia

• Refers to the external area (which is what we usually focus on with tagging)
• Works with size tags (big_labia)
• cum_in_vulva, vulva_penetration, and a number of others don't work very well.

Other thoughts

• I have no idea how fellatio and cunnilingus managed to win over blowjob/licking_penis/penis_in_mouth and licking_pussy (or other equivelents). :(
• pussyboy?
