I'm jealous of people so brazenly attractive they just naturally fall into sexual situations.
I'm reminded of a revelation that turned me off girl-girl porn for a while, having seen a bona-fide lesbian scene and realizing I was totally not invited to that party. Later, a bi friend would point out it's not the orientation that matters: if you're gay but old and not pretty, you're still not invited to the hot scene. (...Unless you have sweet character,¹ or are fantastically rich)
