Advice??

Ill be 39 weeks tomorrow, no signs of labor starting. But...there's an issue? Boyfriend wants a family member of his in the room while I'm in full blown labor. I only want him & my closet sister since my mother isn't apart of my life. He said he needs someone in there for him.. which my sister and him are very close..I'm just uncomfortable knowing I'll be in so much pain and naked from the waste down with someone I'm not absolutely comfortable with. Am I wrong?
