Women working together with women?

Often I wonder if women work better together with other women or with men? Here in webdesign my collegues are both but depending on the number of individuals I work often together with men. So it is kind of lack of expierience. My focus is more on the work not on “private” interests. Looking at female networks my imprssion was, that talking about private female interests such as family, clothing etc. is very important – but not for me. I work and think problem based (if that exsist in english?).
But further in cooperations I often think that women are not so sure and proud of their work. The often ask others (what men seldom do) and are quite difficult making decisions. On the other hand men can often not accept another point of view and try to make their own thing looking the best ever. For this reason I prefer askers who can make decisions, too!
