... for sex:
spending some quality time
making the beast with two backs

...for anal sex:
visiting vegemite valley
riding the chocolate weasel

...for masturbation:
spending some "me" time
polishing Darth Vader's helmet

... for vomiting:
technicolor yawn
driving the porcelain bus

C'mon peeps, post 'em if ya got 'em. Two of each kind, like with Noah.
