my boyfriend wants somebody extra in the bedroom

Katie

iv been with my boyfriend for 8 years now and now we are expecting our first child. The other night he went out and had a few drinks he told me, that he would like to see another man in the bedroom with us or while he watches. I'm not sure how I would feel with another man in the room, I have spoken to him but he said it's in my time and I could pick the person but it looks like he wants a couple to join. What do I do ??
