Being a guy and having super powers would probably mean showing off. Sure anyone can take their girlfriend to terrestrial landmark X, but as a super human you're not just anyone so why not take her someplace fantastic? The only problem is a lot of fantastic places are also fantastically dangerous or otherwise inhospitable to your average person.
Taking someone to Jupiter might seem like a good idea, that is until they're screaming at you from a full body cast for the next six months because their skeleton was crushed to jelly by the gravity. Even if you did constantly ask a person if they could hack being in extreme environments accidents could still happen. It seems as if the spacesuit I made at home was a little shoddy... super tailoring isn't one of my powers, sue me.
