Wear a fanny pack/carry a non-backpack bag as a man.
It's so convenient to have a bag full of stuff on you. Like I'm out and have a headache, boom Aspirin. At dinner and got some food in your teeth, bam flosser. It's very satisfying when a situation comes up and you have the exact thing to solve a problem right there in your bag. But a backpack is too big and bulky and anything smaller becomes a purse and this looks down upon for a man to carry.
I only get the courage to wear it when on a trip where I can overly justify it. Like hiking, or a theme park or convention. I feel like if it was an everyday thing I'd have to explain it or hear about it more than I'd want to.
Get a cross body sling, One of those travel digital nomad things. The brand ones aren't cheap but it's like somewhat fashionable. Maybe that could work?
