I do agree with pom bear that girls can be a lot harder! I have one girl and three boys. The girl is the one that causes the most stress.
You can see other women for the girly things. I find that whatever i do with the kids is determined by their interests anyway, and I'm better finding friends to do the actual things I want to do with.
I think it's sometimes better too, jsut to have individual 1:1 times with the kids and really bond with them that way, especially with a larger family. I go to rugby matches with my oldest son, we've both really got into that and support a team. I've done a foodie weekend away with my daughter, and we cook together a lot. My youngest son loves music, and I help him practice his violin, and take him to concerts. His twin loves cycling, and we do a yearly 10 mile bike ride together, and cycle to the supermarket at weekends when we need shopping.
I don't feel left out with the boys at all, because I don't really see any of their interests being totally gender specific. I can't stand football, but they can do that with their dad, and I take them to football training sessions in the holidays and bugger off for a coffee in peace. But I do ohter stuff with them, so def not left out.
