To hell with 'em, man. I had a lot of people ask the same question to me initially, some people just aren't going to get it regardless unfortunately.
I wear makeup often enough to be notable, spend excess money on ->-bleeped-<- for my hair (including synth hair extensions and stuff of that sort), watch Golden Girls way more than anyone ever should and occasionally help my mom pick out outfits.
And that's just me, my cis boyfriend does bellydance, watches chick flicks, loves baking and wears dresses sometimes. I think the mark of a "real man" is a guy who does whatever he wants, for himself, whether its working on cars or wearing sequined red shorts (one of the many festive things in le boyfriend's closet).
