Flashing In Public

I would like some ladies opinions on what I’ve been starting to do. I’m a 28yo fit guy and for some reason I have urges for random girls to see my dick. For instance I will be in a drivethru and have a same aged if not little older than me female working at the window and I will unzip my pants and let my dick just be hanging out. (I’m 8in and thick btw.) and I know 1or 2 have seen it before because of the smile or I see them look down a few times. It turns me on. There’s also been times where I’m in a parking lot and will start watching porn and jackoff and kinda hope someone walks by and sees or possibly even asks if they can help. I’ve not been approached or called out yet but want to know the reaction you would have if you seen me.
