Quoting Brent: "Unfortunately, I don't have enough first-hand knowledge to say if these are effective."
I must question why, if this last comment is true, you are posting in this thread? If I do not know anything worth contributing or I am not interested in a thread, I ignore it.
Now, clitoris piercings, as usually defined are the various hood piercings. Some women find them very eroticizing and some do not. Probably only about 30% of women are anatomically correct for any of the clit hood piercings.
Removal of the clitoris hood can be done by a skilled plastic surgeon. The one I would recommend is in a very limited, almost retired level of practice now. The is unfortunate as she did beautiful work.
I know for a fact that applying a drop or two of testosterone cypionate, the commonly available injectable form, to the clitoris daily for several weeks will enlarge the clitoris. It needs to be rubbed into the organ. Obviously, the easy timer is to massage the clitoris to orgasm.
The amount of the hormone being applied is so small that none of the bad side effects that the bodybuilders suffer will be observed.
When the application is stopped, the clitoris will shrink to some degree before the size stabilizes. Most women will retain about 2/3 of the size gain.
