The tag implication #42804 penises_crossing -> frottage has been rejected.
Reason: Crossing penises seems to involve frottage in all the (few) images with the tag. Maybe penises_crossing is too vague and should be aliased to frottage instead? I don't have an opinion personally.
EDIT: The tag implication penises_crossing -> frottage (forum #323007) has been rejected by @bitWolfy.
