create alias penises_touching (1204) -> penis_on_penis (2)
create alias touching_penises (0) -> penis_on_penis (2)
create implication frottage (17221) -> penis_on_penis (2)

Reason: penises_touching and touching_penises are the same thing as penis_on_penis. However, frottage does necessarily include penis_on_penis.
