about converting to Judaism?

Not a bris milah but a ritual called hatafas dam bris will be performed. Which is where they take a drop of blood.

All the above are correct but I have to mention one warning. There is a small percentage of American men who have been circumcised in a way that leaves part of the foreskin attached. When this is the case, that residual foreskin is removed by real circumcision.

You should be able to see if there is some foreskin still attached. If not, then just a drop or two of blood is drawn.

Only symbolic circumcision (hatafat dam brit), i.e., taking a drop of blood required and of course, immersion in the ritual bath (mikveh).

You do, but it's only a symbolic circumcision, not a literal one.

yes, but it is nothing more than going to get pricked in the prick with a pricker, by....well, mine wasn't a prick....but ya get the idea none the less

it will be a ritual drawing of blood

it doesn't really hurt
