Masculine: stereotypically, technical cultures have an intense competitive focus on functionality and a dismissal of “soft” skills like communication (I’ve personally tended to hang out in the areas of the engineering world where that’s not true – and have found most of the engineering world to not be like this at all). Confucianism-based cultures tend to (also stereotypically) have very strictly defined gender roles. Note that all-female groups can also be masculine (as I understand the Hofstede cultural dimension for that word) if they promote a single image of what womanhood should be and have an almost militant focus on achieving it.

Feminine: Examples of this might be the culture present in support groups and mediation sesssions, though I haven’t really had direct exposure to those myself so I’m mostly guessing here. LGBT groups tend to be very supportive of a wide range of gender identities. Overly feminine cultures bother me just as much as overly masculine ones do – sitting in the middle of a group talking about who likes who is about equal to sitting in the middle of a group talking about who has more video game kills, and in both cases I’d prefer to go off by myself and read a book.

All the cultures I’ve encountered have both masculine and feminine elements; I think you’re always going to find a mix, regardless of which side a particular culture tends towards. For instance, many of the software projects I’m involved with lean towards the masculine with a focus on technical functionality, but also greatly value community and consensus-building even if it temporarily appears to make the technical progress “slow down.” It’s a balance.

Not sure if this helps, but those are my (not particularly fully formed) thoughts on the subject.
