Why girls don't feel shame in wearing bikini?

I want to ask why girls don't shy in bikini, monokini and other swimsuit. Because in all these, little part of hip, thighs and little part of boobs and cleavage in bra are visible. And all these parts of body are private and sexual part. all these parts can seduce a man when he see any of these parts of a girl. I m man, and I get sexually attracted to those parts. We men don't show our hip or penis. A girl can also swim and take bath with full cloths in public. But they don't shy, infact they enjoy in showing. And say it is called freedom. Sorry girls, just curious.

And in last, I just want to say sorry to everyone if I asked disrespectful question especially girls. Actually this question was moving in my dirty mind from several days so I was curious to know about it from a girl side. Every girl have freedom whatever they want to do. And every boy have freedom to interpret the way he wants to interpret. It was just my point of view.
