I'd like to think there's an easy way to get women into bed just by asking like this.

But I think it's VERY unlikely to happen, even if you are a really good looking man or have 8 inches down the leg of your shorts or whatever. And any woman who does dive into bed that quickly is probably a bar-hopping skank ho who fucks all sorts of men, so who knows what she's got in her cunt that you don't want on your cock.
