I think the only 'girly' subjects I like to discuss are comparing children type conversations which I have something to contribute to. Talking about painting nails would bore me to tears.
I'm really not a girly person though, I HATE clothes shopping for example.
I've avoided going to spas with my friends as I really don't enjoy that kind of thing.
There are advantages of having a more male-like brain, though. I'm much better at navigating than my friends!
