It was brought up in a comic a few years ago that Superman has an extraordinary super ability that he hardly ever mentions (I forget where, but it was within the last 5 years.) which is "supersensitivity" inso that although as he is invulnerable when he is shot by bullets and such that the pain involved is actually hundreds if not thousands of times more painful than a human or a non enhanced kryptonian would experience from the same wound, which really puts him on par with Daredevil's hurting himself hundreds of times worse than the people he punches during the course of his escapades because of his enhanced sensory apparatus. I agree that Lois has a healthy sex life, but Clark really can't enjoy himself (selfishly) without losing control (briefly) during the course of orgasm, however it's more than likely that she can give him handjobs without fear of losing limb or life, or being selfish. Who said Wonder Woman is a virgin? it was clearly made out in Justice league Taskforce that they were all loving the gay sex on themiscyria and she also spent 40,000 years screwing Superman when they were trapped in a pocket dimension nearer the end of last century.
