Is the O-Shot painful?

People ask whether the O-Shot hurts hoping for a plain yes or no. The two published answers below do not match, and that mismatch is the useful part of the question.
Two sources, two moods
www.healthline.com quotes a founder as saying "The O-Shot is not painful at all." greatist.com is more guarded. In theory, it says, the injection shouldn't cause horrible pain since you will be numb, but knowing what's going on down there may freak you out.
Neither answer is about your visit
"Not painful at all" is one person's description, and the second source hedges with "in theory." Neither one tells you how your own visit will feel. The second source also points past pain to how unsettling the idea itself can be, which is worth weighing before you book.
Further reading
An explainer on the O-Shot and PRP is the plainest place to start. A lay account is titled what to know about the O-Shot, and a review on The Niche covers stabs at sexual enhancement. One post argues in its title that the O shot is untested with a sketchy past.
Ask who numbs and who injects
Do not judge comfort from a quote, and never attempt any numbing or injecting yourself. Ask the clinic what numbing they use and who performs the injection. Ask before you book, not once you are in the room.
Painless to one, unsettling to another
A treatment that one source calls painless and another calls unsettling deserves a direct conversation with the person who will do it, before you agree to anything.
