What is something the opposite sex can do more of / better / exclusively / more efficiently / more accessibly etc than your gender, that you are jealous of? Other commenters belonging to that gender, does this person's jealousy of this aspect make sense to you?

Or in other words, when someone points out an "advantage" of being your sex that their sex do not have to the same extent or at all, do you think they make a good point that this is indeed an advantage you have?
