Rob, that is probably a common side effect. If you haven't done a lot of pumping, or if the pills were a failure, then your first few chemical erections may be a little uncomfortable. Gotta consider that that part of the system has been out of the loop for a while. If it continues, followup with a doc, it may be something unrelated like a urinary infection.
