Hi Mathew,any piercings or tatoos are a big no no for JWs. They do not want you to have your own identity. They insist on you following their rules to the latter. As has been said you will have been loved bombed. That is what they do to anyone new. And certainly once a person gets baptised you have to abide by all Watchtowers rules. You will find them all listed, just google it. The org is dying, so they are desperate to get anyone new as a member.
Please make sure you research JWs properly, you will be appalled when you learn more about them.
