Naw, nothing erotic about it, for me anyway. I once warned a squeamish coworker against being in the delivery room if he and his wife wanted to ever have sex again (he was *really* squeamish). His wife overheard and didn't seem to appreciate my attitude, but geez, this guy would get queasy watching me suck down a cup o' noodles.
On a lighter side, when my stepdaughter had her second kid, her husband was in there taking still shots. Later, when the film was developed, her 3 yr old was running around the house waving the shot of her with her legs in the air and betadine all over her ass yelling "STICKY BUTT!! STICKY BUTT!!"
