Is this normal or am i just asking for trouble?

Ok I'm currently dating a guy who seemed "normal" I guess you could say at first. Now that we're in a relationship things are starting to come out to light and I'm not too sure I can handle how big of a freak he really is. I'm a freak, also but he pushes the boundaries. He's really into pissing, shitting, puking, beating (not face just ass area), control, HARD biting, name calling and stuff like that. I guess what I'm trying to say is I'm scared that these fetishes of his are going to spill over from the bedroom/private play into our every day lives. Coming from an abused childhood I'm not sure I can seperate the two. Any advice will be appreciated! thanks!
