Sadly, the human species has not changed to any really noticeable degree in the last 10,000+ years. We're still the same species who lived in caved, threw rocks at our own shadows, etc.
Basically, we aren't built able to, biologically, recognise the difference between a real woman in the flesh, looking 'quite pleased' to see you, and a picture on a website designed to sell you something.
Its an annoying problem, frankly, and I do respond with anger when I feel like something is trying to advertise to me via 'mini-me'.
Anywho, is it right for girl gamers to use their bodies to attract attention. From the context, it seems you mean non pervy attention. I don't think using your bodies is the right way to get it, because you'll only have pervy attention, not proper attention. To be honest, 99.5+% of male gamers don't get listened to either, we get 'grouped' into catch-all audiences.
