Calculated risk/reward ratio. If I wear a mask when seeing a sex provider it is a "one on one" slight Covid risk, but the reward is worth the risk to me. In general public, especially in large groups of people, the Covid risk is much higher, with no reward for me to not wear a mask, except possibly to avoid people like nuddahshoah (in his above post) pointing their fingers at me in disgust for being a "sheep". What is it their business what I do that doesn't affect them? Fuck 'em!.
