There's a huge difference between a push up bra and getting breast implants. Putting on makeup or a push up are temporary. If you've ever seen how they put breast implants in... Well, lets just say I'd rather see a woman putting on a push up than envision the bag getting jammed into her chest every time I see her with her top off. But the real problem is, I don't think implants or other surgeries do anything to attract men. I like women with big boobs, but I know plenty of guys who don't. Men have enough varying tastes that it's not worth getting surgery to attract one. Surgery is generally by women, for women, and, to beat a dead horse, I think its really due to the media and the way they perceive beauty.
Sorry for dragging this conversation exactly where you didn't want it to go, but... Eh, no I'm not sorry. It evolved naturally. See how that works?
if most men like larger breasts. I think men just like breasts in general. I'm not all that picky, a nice small breast is fine with me.
I was just pointing out that there's a world of difference between an article of clothing and a life altering surgery.
