A few lightning bugs are still lighting up the fields and forests these hot summer nights. The males fly around and look for the flightless females lying in the grass. The males drop down to mate, and then the female eats the male. Whoa! That is not a happy ending to the story. It turns out that sex (for the fireflies) is dukkha ("bummer!").
This reminds me of a chant.
Separation from the liked is dukkha.
Association with the disliked is dukkha.
Not attaining one's wishes is dukkha.
Well, we could apply all of these to our sexual relationship(s).
Separation from the beloved is (sometimes) distressing and creates a longing.
Association with the disliked (state of aloneness and yearning) creates a desire for change.
Not attaining one's wishes (i will leave the sexual details to your imagination) can create disappointment.
