Men of drowned in sound... And women also i guess, if we're going to suspend disbelief for a second:
Imagine you had a little baba and it needed it's nappy changed. However, the only nappy changing facilities in whichever pub/restaurant/tourist attraction you happened to be visiting were in the female toilets. Would you feel weird about going in there to change the nappy?

I don't think I would. Talk about this.
