Have you had a baby?  That informs this dialog.
Yes, but the moms (typically) pick their OBs, and have established relationships with them over the course of many months....so there's a relationship there.  If they felt uncomfortable with that OB, they wouldnt pick them.
It's not the same thing as showing up in labor, in pain, scared - and then a male nurse is what you are given - a guy who is going to be doing your vag exams, seeing you naked, helping you figure out how to push effectively. Plus, If you unexpectedly end up in the hospital with a traumatic situation - ie preterm labor - you want to feel as emotionally safe as possible.  I now work in the NICU where a lot of moms have birth trauma.
I'm not saying a male nurse isn't capable of the job - he is - I am saying I think it's completely fair and advisable to make mom feel emotionally safe at perhaps the most vulnerable time in her life
