Whenever we are with a friend of his, he starts making innuendo or just flat out stating what he wants to do to me, like biting etc. I don't think this is appropriate in front of other people;at any rate it is really awkward. I've told him how i felt about it before and then he went ahead with it anyway and acted like he forgot. Apparently this is the theme he takes everytime i mention in private that he shouldnt do that. So when its happening, how can i tell him to quit it with the tacky sexual innuendo before he bombs every conversation i have?
