Looking can’t be helped, but it must be so subtle that the eyes don’t follow and the head doesn’t turn. Usually comments would be unacceptable too. After many years of marriage, sometimes comments are made jokingly when someone is over the top and we are people watching, or I may give a beautiful woman a compliment. Woman to woman is okay, but if he said it, I’d probably feel hurt. He’d get jealous if I commented about a man being attractive, too.
