I find bum implants slightly weirder just for the fact you would be sitting on them. I can't explain why it just makes me go all goosey the thought of it. Maybe its the thought of all the persons weight being on these implants day in and day out. Saying that though I do find the thought of breast implants weird too so maybe bum implants are equally weird in my head. And before anyone mentally shoots me, I don't think anyone who gets them is weird or it is any of my business what other people do, it's just an opinion about it in general!
