My boyfriend likes to either be dominanted or be dominant in bed. I have figured out what turns him on. I on the other hand like it without the role playing every time. He either wants to pretend that I'm raping him or that I'm this naughty girl who is a stranger to him. This is usually 90% of the time. He also likes to call me names like whore, bitch, slut. Is this normal for a person in love to call his girlfriend these names in bed?
