I love the way this is normalised now and also how 'liberated' ladies just casually drop it in conversation online/offline how they have a nice collection and all the lovely things they do. 
So...you get a rubber/plastic artificial phallus and ram it repeatedly into your vagina while pretending it's the member of an absent lover and you do that to pleasure/excite yourself in order to get the drug-like hit of an orgasm for its own sake. It's normal because we've got used to it, but it's intrinsically weird. Imagine no one did it and you invented it and casually brought it up at a dinner party. 'Oh what, you mean you don't stick anything up yours? You should try it, it's great'. Or a man, in civilized company, maybe a gay man saying how much he loved shoving one up his bum. What's the difference? Or a straight man saying what fun he had last night with his artificial rubber vagina. And how he had a party with all his silly mates and they got drunk and sold and compared artificial rubber masturbation devices to each other. I can hear the cat call 'Pervs!' 
Think about what you're doing. Your mind wasnt' designed to see your body use itself for it's own pleasure. It just wasn't. Get off the society-norm train. Think for yourself. Society and its hedonistic norms don't care about the mental outcomes for you. 
A rubber artificial man-sausage. Up your choofchoof? Get a grip.
