Funny you should ask.
I'm actually one of the draw fags working on a comic from the hyw thread.
I say men can easily write women as equals, it's the obsession with being feminist or anti-feminist that makes it difficult, nothing inherent to a female character makes it difficult.
Personally I never have any trouble writing my girls as equal to my guys.
I like sex and sexuality, male and female, both are worth exploring without over shadowing characterization outside of it.
The only reason comic pros are bad at it is the fact they're so obsessed with being feminist they've refused to learn how to be fun and sexy without being insulting to any involved parties.
