I heard somewhere that woman with fake breasts are more sexual than women who have natural breasts. Im pretty sure I heard it on television, so ya know it must be true. I think it boils down aesthetics and feel. The silcon breast may look more pleasing to the eye, but it wont be to the touch. the natural breast will feel better, but it might not be as pleasing to the eye. Its definately a personality defining question :-p. Ultimately you have to go with natural breasts, for me personally, i just like to keep things natural. (besides, seems really weird to me to have a bag of anything in your body that you werent born with... would definately be an adjustment :-/)
