Don't worry your fine... The first time does freak you out a bit hahaa. I remember the feeling of pulling the little teeth out of the top layer of the skin on my finger, didn't bleed at all though...
the bite is sooo minute...its your first layer of skin and you cant even feel it because are fingers are round and plump the pinchers cant get a good grip... i have been bit dozens of times...lol its not a big deal.
