I'm not a downvoter but I think your very first premise is really flawed. A blanket statement saying men (or at least the ones you meet) are boring is kind of not recognizing the massive diversity of people. But it sort of gets clearer when you say next that you like the flirty subtext of talking with women, and then that starts sounding a bit creepy, especially when you are adding in the over emphasized insisitence its not about dating/sex.

I find it harder to make friends with males because it's often hard to find a good connection. I'm 47. But I have made good friends with other males once we find a groove (often based around humour)

I've often been surprised about the things other males think about once they open up. Initially some males can seem quite one dimensional.
