My husband is wanting to try new things .. but...

I'm seven months pregnant... all I have on my mind right now is that I'm high risk, pregnant, getting induced at my Dr's leisure for baby's safety and yet all my husband cares about is how my heart isn't into being sexually experimental. Not that I don't want to be ... I mean I slightly dont... but still. He's asked me if I want to have sex with another guy while he watches! Wtf.. or three some with a guy! He even told me to pick one out! I said no way in hell! Then he asked me if I wanted to watch him have sex with another girl.... that really hurt. I didn't even answer him. I couldnt.... he wants to try anal, and we have before but I can't get into it and it hurts me.... and he wants to get toys. Fine.... Fine not really against that.... but still! I feel like he doesn't want to be with me. I want to just tell him to go off and find a girl that will make him sexually happy and I'll just be here emotionally... I know that after I have my baby she's going to be all the world I'll need. What do I do? I'm so torn. He won't leave this alone.... what do I do?! Help any advice is welcome. I tried talking to him about how it makes me feel... he doesn't seem to stop though still...
