No flame intended. Honest question. Never thought about the gender of my kids being a privacy thing.
Ontopic: As a parent I (we) try not to restrain things like screen use. Instead we actively promote all other forms of spending time we prefer more. This means I usually enter the room before my kids get up and put the devices away and put other toys in sight. My wife is a montessori (method) teacher which makes her quite skilled at knowing which kind of toys/lessons our kids like at what time in their life. Meaning each couple of weeks the things we prepare change. Result is they usually first pick a bit of everything in plain sight and only after, at the end of day, ask for a device. We didn’t tell them not to, it is just they really like their puzzles, painting, and what have you. In real life preparing means putting things in sight instead of in a closet and one of us being downstairs before the kids is normal as well. Not much effort there.
Disclaimer: my oldest is only 3 right now. Older kids may be entirely different though I believe promoting better options has a better effect than restraining the negative ones.
