[18+, also not Supergirl or Lois] It's an old meta discussion speculating on whether Superman's powers would also effect the force of his orgasm, considering that it's been likened (physiologically speaking) to a type of epilectic fit wherein one loses control of one's muscles and in the comics he's been known to accidentally leave his fingerprints in steel and hardened concrete. And what the implications of that might be if he were to have sex with an ordinary human woman "designated LL for convenience".
