Try the100.io as your lfg tool. The community there is mostly mature, helpful, and you can find pleasant gamers from all walks of life. I use the100.io for all my co-op endgame activities and have yet to have a less than positive experience due to the fact I have a vagina. Sure, comments have been made, but they're generally not creepy and mostly due to the initial shock when we start. I've made some good online friends through that tool and they respect that my bf and I usually play together. When I get invites it's usually for two.
