My church has about a 98% compliance rate with masks. (The congregation has been slowly letting up with how long they wear them and whether they're distancing too. Crazily, people were masking and distancing at the start).
I happen to go to our men's meeting on Thursday. Zero masks. These are the same men in the regular service on Sundays.
You can probably draw reasonable conclusions from this.
Mask enforcement is 100% from women and gay men.
