But I think that the durability/resistance of the flesh would preclude sex. When you ease into a tight pussy, you feel a fair bit of resistance. Not a lot, not enough to make pushing in particularly difficult or painful (for the guy at least), but there is some. Scale that up to a top tier super heroine and it could be that a normal guy couldn't press in.
OR
play with a girls tits and you can jiggle them around a fair bit. Flesh is squishy and you can move it around a fair bit, it only really has resistance when it reaches its limits and thats when it also hurts. e.g. would Wonder woman feel Soft, or is her flesh like iron. Or if lois kissed Superman, do his lips deform around hers? I think they would. If you relax you lips, you can move them about a fair bit. I think it would be the same for most superhumans. You can deform their flesh just as easily as a regular human if the muscle underneath is relaxed, but not to the point it would hurt or damage them.
i.e. you could punch wonder Womans boobs and they would jiggle, but not be hurt. Same for sex. You could fuck her, but if she tensed up, even involuntary, your dick would be crush.
And the third alternative
Superheroes can have sex, just dont think about it to hard.
