In the old days, in some cultures (most especially Europe where the church ruled everything) the displaying of the genitals was considered unsightly and inappropriate, even between married couples. So having your grotesquely swollen vagina exposed while birthing was something only the midwife, later doctor, should see.
Why do they never let the husband be with the wife for the births?? Not many manwhas do, like theres no way im giving birth without squeezing my husbands hand til it hurts
