How to get a fetish like big boobs ? Well psychological studys show most boys that are into big boobs love strong woman and see size a power on a subconscious level, after Sigmund Freuds theorys about sex some girls like the idea of a " daddy " or big brother type of male, a person that is caring and loving and protective mostly out of deep desire to feel safe, the other side version " mommy " or big sister type is the same, just from male pov so the breast expansion fetish fits well with hypnosis both is powerplay, same with monstergirls and other fetish stuff most boys with this kink are not very confident and prefer the woman to make the first step in other words psychological the " i love big boobs " is a sign that you are a bit shy and probably a nerd, since i am a shy guy and a nerd i can say jeah that fits. On the other side if you realy want to know more about how you get a fetish, there are some books about it, maybe study psychology you will be suprised how everything in life is always about sex in some way... for real we are all very strange animals, humans, lol besides that boobs on a subconscous level have the pupose the ass used to have to attract males since humans walk on 2 legs and do not see the ass all the time the boobs evolved to look like ass, so basicaly boobs fetish is the evolution of the ass fetish, both exist to signal " this woman is fertile" so as bigger the boobs as more feeling of safety and power. Basicaly... dude for real, do you realy want to learn all about the psychology of sex... it is a big topic... since this is a porn page, not a science chat room maybe i told you enough, you are welcome
