My x-boyfriend used to ask me to lick his feet and suck his toe during out lovemaking and my xx-boyfriend used to finger my ass, not only fingering, but he used to put ALL his fingers up my ass and my xxx-boyfriend used to spit in my mouth while kissing each other and my xxxx-boyfriend used to lick my armpits to get a hardon All of them used to tell me that these things are normal to enhance sex, and i used to accept their words because i loved them all, although i find it a little bit strange But, my current boyfriend asks me to lay down on my back while he chew and byte my clitoris, I don't mind if he licks my pussy, and it'd ok if he played with my clit to arouse me, but he hurts me while chewing my clit, and i cannot tell him to stop, because he will be angry Why all these things happen to me, why I can't get a normal boyfriend?
