Can I do bjj If I have a pierce ear?

Lmao trust me you can do bjj if you have a piercing for sure. I have to guaged ears ,both size 7/8in , a lip ring , and 3 normal earrings . I take all my piercing off before i train, i dont cover them up with tape or anything and i've been training for a year and did two tournaments (place first!) and the refs. or judges didnt say anything nor cared about them, so in conclusion YES you can
