My boyfriend recently told me that I am shy in bed. I don't like being on top and we've already had sex in the dark. I think he wants me to be more aggressive but I don't know how, as this is the first guy I've had sex with. He kind of hinted that sex was boring to him and now he doesn't want to have sex anymore. I like kissing him when we have sex but being on top, he won't let me kiss him. I really need help on this. I don't know what to do.
