I want to get my navel pierced by a proffesional but i want to know the riscks of getting a serious disease?

he is a proffessional but i am still scared, like what if the needle is new and still has hiv or other bad things.. i don't know.. it's not the infections that scare me.. i would put alcohol there but the diseases.. am i being paranoid? also the guy is gonna do it home and won't ask for an id since i am not 18 yet.. what should i do?

I had mine done at a tattoo place that was clean, but it still got infected. That's a hard place to keep clean b/c it hits your waistband and gets moved around all the time. I cleaned mine religiously and it still never healed properly so I ended up taking it out after a few months.

Having him come over to your home does not sound professional at all. Going to the actual store sounds safer. If he does not use a new needle I would not go ahead with it. If the needle has never been used before there's nothing to worry about. I would think about going to someone else instead. It sounds like the kind of person that does not care about anything other than getting paid.
