Why do men only use us for our body and throw us away after they are done with us?

I think by reading some of your other questions that maybe your choice of boyfriends is at fault, maybe you should set your sights a little higher and find someone who respects you more.

Because they can.  We let them by being easy.  Yes easy.  We let them have whatever they want including sex.  It takes a while to genuinly love somebody.  Some of us think that we have to give him sex or else he wont love us.  Guys who havent had the chance to know u mentally will not keep u around.  They will use u from time to time. 

May be your body is somehow sweeter than honey

I am not like that make friendship with me ok
