I do, but I'm also a nympho, so I like sex all the time. And I like it rough and angry, so makeup sex is right up my alley. Both scenarios are plausible, but not all Cancers are alike. Some may need more affection than others to feel secure enough to be intimate again. Others may want you to get down on your knees and grovel first. It depends on what you did, or the severity of the argument.
I've had relationships with 2 Cancers so far. The first one, was all about make-up sex and it was hot, too. Second, well can't really give opinion since we haven't made up yet.
