Question about eating pussy

Me and one of my female friends were having a convo about eating pussy and she was like her ex boyfriend would eat her while she was on her period. She was like she would take a shower and then put a tampon in and he would just lick on her clit to make her cum. I was like thats nasty fuck because you're bleeding. She said that you don't see any blood because the tampon should soak it up. To me thats nasty because one your bleeding. I told her she is nasty for letting him do it and he was/is nasty for doing it. Whats even worse I'm sure he would kiss her after is he done. My question is ladies would you want your man to eat you while you're on your period? And guys would you do it? My answer is hell naw lol
