sheath touching vulva

When a penile sheath is physically touching a vulva. This tag is distinct from "sheath_pressing" as sheath_pressing implies the penis is being exposed as the sheath is pressed backwards. This tag may apply regardless of whether the vulva is penetrated or not. Use additional tags such as "-penetration" and/or "fully_sheathed" to find art where the sheath is touching the vulva without penetration. Generally this tag may appear with "imminent_penetration" or with "imminent_sex."

Needs to be merged with "sheath_on_pussy"
