What kind of experience is it to have oral surgery done?

Depends on procedure: Performed: from orthognathic surgery, parotid glad removal, and temporomandibular joint replacement to implants and wisdom teeth removal - the extent of the surgery will dictate overall experience. However, with either comfortable sedation or general anesthesia, the experience during the surgery will be consistent - comfortable, relaxing, often euphoric.

It's OK : As long as you go to a board certified oral surgeon with a good reputation the experience should be a good one. I suggest IV sedation for most oral surgery.
