[Harry Potter] What are some good nsfw spells and potions that every adult wizard and witch should know?

I just graduated from Hogwarts and going steady with my boo from Beauxbatons.. What are some good potions and incantations that I should put in my repertoire?

Well, engorgio can be used for more than just the obvious. For that matter, so can reducio. 

Polyjuice potion *might* be illegal, but it will absolutely spice things up. If you're creative enough, any transfiguration, up to and including ducklifors can be used in the bedroom.
