As a women you know guys are going to stare at your boobs. How would you rather they do it?

Just a quick glance is fine. Women are also checking out your arse or your bulge. It's just we are a 100% better at not being noticed 😂

How many ways are there? I think you're missing the point. It's not hard to look away once making an involuntary glance. Just do that, unless you don't care about being respectful.
