I'm old enough to remember when women insisted that it was only fair that they be permitted access to the men's locker room while they are changing their clothes. It was controversial but they got it and I'm sure that for their efforts they got to see a lot of naked men. I'll bet even then though that they wanted no men in their own spaces.
I interned in 1976 for a radio station, the same year MLB mandated women could access their locker rooms. In front of every locker, the team had installed a shower curtain which wrapped around the front of the locker stall so the player could have privacy to dress and undress. I was having an interview with a player when he motioned to me to get a little closer to him. In one whoosh, he had slid the shower curtain around the two of us. As he did this, he said “Step into my office”. It broke my concentration but he went right ahead with the interview.
I like the way the NCAA has it where there is a large interview room where the coach and key players are paraded out for the entire group of reporters. It’s completely gender-fair and allows the players to shower and dress without prying eyes from the media. Women complained that they could miss out on locker room tension if confined to an interview room but, you know what?, the media is not entitled to everything said in a dressing room - men’s or women’s.
