It seems like penis smelling will be approved so this proposal should be "smelling" instead of "sniffing." We should strive for as much continuity as possible with tag names Also, I don't think we would need an umbrella "crotch smelling" tag. Instead we should have both "penis smelling" and "pussy smelling." The two of them together would pretty much cover everything that "crotch smelling" would cover

A crotch is not a penis.
