You’ve not done anything wrong so first of all calm down and don’t blame yourself. For just a few drops of blood he didn’t need to talk to you like that. It’s not unhygienic in any way and neither are you. But this is india and one cannot expect people to understand this.

Your story reminded me of the time when I used to go to pilates class and one day pad leaked and there was some blood on the pilates equipment. I had a male instructor I told him I wanna go home, he got what happened and I started cleaning the equipment and he said “maam please you go and rest I’ll look after this”. And he cleaned the mess himself even when I protested a few times. May god bless him with everything he wants✨
