I'm a women and personaly I love it when a guy says maam to me. However there are a group of women who are usualywho want to be younger and calling them maam sometime offends them because it can be a sign of old age, like they think only the old people get called maam. But for the most part when you call a women maam they think how polite and thoughtfull, so go a head and use it, you'll get more happiness then ridicule.
