piercing of the nipple CAN, in SOME cases, lead to near constant erectness.. put it can also cause swelling, local tissue irritation, etc..
this is an option that may work for a few, but not many.
******************************
with respect to yohimburn.. the nipple puffyness issue is one of the less certain effects.. some people get complete reduction others only a little..
IF you dont see quick results with respect to NIPPLE PUFFYNESS(within 1-2wk.. making sure to take at least 2 days off every 5)>>> > LOWER THE DOSAGE to minimize water retention (as low as 1/8 even 1/16) and just run longer.. this is the approach the we THINK will work better for the so called "non-responders"..
