It may be impossible to do piercing with forks but using dull things is much safer than using sharp objects because dull needle will not do any internal damage as it will slide in pushing everything from its way without even causing significant pain bbq skewer or knitting needle is most suitable for that It may be even less painful than sharp needle.

One time it happened to me when I hit the huge dull nail wit my my leg and it went all inside while the only thing I felt was that something touched my bone. There was no pain an no blood at all. People often fall on various dull objects and get skewered but they neither bleed much neither suffer any significant damage.

Considering infections it is not really that probable unless you have diabetes or other diseases. All that matters is not to stuff some hard dirt (like big pieces of rust) in your body or else it will be really bad as there will be no way to get them out easily.

On the other hand, I would not recommend cutting yourself ever because this will leave scars to take lots of time to heal and later it will bleed and hurt more tha in the begining.
