I don't see the division. It sounds more like a stereotype especially when you have gay men who are attracted to other men as straight men are attracted to women. So, I'd assume it's not specific to the object of attraction just attraction itself. Vis versa. The same intensity of attraction to another woman for a lesbian would be the same if a straight women looked at a guy.
So, instead of women dressing up but not men, since attraction is not biased in those regards, maybe both should be dressed up so either won't be tempted whether between men, or women, or opposite (using human sexuality as an example that sexuality isn't sex dependent in its experience and normality).
I heard an example on a TED Talk about the body not knowing the difference if you're excited or being anxious. So, if someone has stage fright, they can tell themselves they are excited and the symptoms are the same as being scared. It's changing one's mindset. Instead of seeing men as more lustful then women, change the mindset to see sexual attraction as not sex-dependent (like the body doesn't know what's anxiety and what's excited).
I think that people would end up better that way without division between men and women roles. At least in the states.
