That inverse notation is only used when things cancel out under some sort of composition or multiplication. In this context the identity would have to be no condom but composition of condoms (i.e. doublebagging) doesn't result in cancellation.

That notation would only make sense if you could do stuff like this
[math]M_1\supset_1^3\supset_1^{-2}F = M_1\supset_1 F[/math]

See picture. Do you have another solution that doesn't involve double bagging? Keep in mind that since there are only two condoms. with two sides each (i.e. four sides total), each person must be assigned their own side of a condom. That means that the woman can't use both condoms separately.
