What does it mean when a guy takes off your bra?

It means either he is immature or he wants to have some hardcore sex with your boobs. (if you have any) or he just wants to observe the human female body. or he wants to get you pregnant. if this happened then just say that you are too young for (if you are under the ages of 18) sex. or if you are immature too, well, goodluck with your private moment together, im sure it will be"breathe taking' and "enjoyable".
