The male version of a feminist is a feminist.
There are male feminists and female masculists.
There are feminine female feminists, masculine female masculists, emasculated male feminists and macsculine male masculists.

And that's just my little street!

I just can't abide "masculinist." It sounds like a diminutive. Masculette?

Of course, we all know that a masculinist is one who plays the masculin, a larger, heavier version of the masculia.
