At one time in China foot binding was practiced and that resulted in women with tiny deformed "lotus" feet. They were believed to be highly erotic. Obviously for those men who grew up thinking it was so, it was real turn on. But today it sounds ridiculous.
Janaan has rightly pointed out that where breasts are seen everyday and women don't hide them, they are not considered a turn on at all. In some of these countries, for example I believe in Mali, a woman's thighs are considered erotic.
Biologically the purpose of breasts is to nurture one's young, not to sell motor cars!!!!! That comes from our own cultural bias.
I dunno hey penises are really ugly (so I hear) but these days me and my friend are wondering about the size of the average shlong. I was asking my male friends and they were showing me different ways of measuring how big a guys shlong is.
ummm my view..well lets say like i read somewhere that medically its normal for a man to feel sexual (u know what i mean) 4 to 6 times a week. maybe its that time when male looks for the way how to setisfy them self.
on the other hand, the normal ratio for the female is 1 to 2 times in 2 months. so if even they feel that way its negligible. & two more things, first “sharam” is a part of nature of woman, so if even they feel that way once in blue moon, they kill that feeling. secondly i dont think comparing breasts & pennis is similar, u can compare penis to vigina, not breats, breats are somehwat better, the other two things are much more ugly (just an opinion)
