In my experience, the social hierarchy of small groups of women is dictated by will, or charisma. Among my friends, the most strong-willed or the most charming tend to get their agendas forward if there is any conflict over a group decision. In one circle, the defacto leader is less like our friends, and more like me. She's the most charming AND the most willful. I alone in the entire world seem immune to her application of charm. She can outlast me in a standoff though.
Anyway, she and I are the least sexually conservative, though not the most promiscuous. She and I encounter more big dicks than the others. Because she and I want to talk about details, the group talks about details. It gets very loud and giggly over a bottle of wine if anyone in our group starts gossiping about meeting a new man.
None of my other groups of friends are remotely interested in talking about sex unless it is a clinical discussion, or the group of friends is male. My guy friends will talk to me in detail about sex, though not in as detailed a way as that one group of women. When they do give more detail than usual, typically in order to get advice about a problem, or explain an incident they need to sort through, they seem nervous about my participation in the discussion. I am treated like a dude, until we talk about sex.
When I told female friends about a dude I encountered with an oddly shaped micro penis, they looked sympathetic. They gasped. They were shocked and horrified. When I told the story to guys or mixed company, they laughed. When I tell women about giant cocks, they want to know more, and they have a lot of questions. When I tell men, they laugh, or say "Dayum!" When I show them with my hands, sometimes they laugh, sometimes they exclaim. They have never treated me any differently, though one I used to fuck frequently refers to himself as having a small one, something he didn't used to do. He says he always seems to fuck women right after they have had a big dick. He wasn't nearly the biggest hung, but his erection is a great size for me, and considered small by few. He's only ever met one dude who fucked me, and that's because I married that one. He has no knowledge of my ex-husband's dimensions. My one circle of home girls do, though.
