I don't think I'm a prude, but I feel a bit self-conscious ordering "A porn star martini, please". It's a shame because I quite like them.
We went into a "family-friendly" bar from a chain called "The Lounges" (every one has a different name, like Albero Lounge, Edmundo Lounge, etc) and on the menu there it says "Passion Fruit Martini... a cocktail fit for a movie star", which nicely conveys the idea without everyone having to explain to their curious 7-year-old reading the menu what a porn star is.
(The same chain has also renamed Sex On The Beach" to "Lounge On The Beach"... that one wouldn't put me off so much in the original form, but I don't like peach flavour drinks anyway 😂.)
