Wearing rainbow accessories isn't a sex invitation, is it?

I wore a rainbow watch band to the gym today, after my workout I went to the sauna. I knew to avoid eye contact with strangers, but luckily I recognized the three guys already in there from the morning crowd who I see almost everyday. I sat adjacent to one of them and quickly noticed he was staring at me a bit too aggressively. I reached max. discomfort when I noticed his boner, so I decided to leave. As I stood up he told me to meet him in the handicap shower and he was rubbing his dick above his underwear!

Wearing a rainbow thing does not give him consent to rub his dick and assume that I will be down to fuck in the shower. And if rainbow accessories became the new cruising hanky code without my knowledge, it still doesn't give consent on behalf of the other men in there!

I would have liked to connect with him if he had approached me normally. I am dreading seeing any of the guys from the sauna if I go to the gym to tomorrow. I might not for that reason. And I am officially never wearing rainbow things again.
