Do girls discuss their man's "size?"?

[Nicholas M]

I've been with this girl for 6 months. We've started having sex on a normal basis, and I heard some of her friends talking about thier man's size. I'm 6in when erect, and my gf tells me I shouldn't worry about being small, but I was just wondering if all girls do this or if her friends are just weird?

all girls do it just like men talk about women
