isn't sex pleasurable enough without putting menthol on your penis? your partner may not like this cooling sensation either. is it harmful? i suspect it is fine but i seriously doubt that the company tested this product on genitals. it is usually for sore joints and muscles. one can have allergic or adverse responses to any product that is used for something that it was not indeed to be used on so obviously your menthol days may be over. this unpleasant sensation should end soon. try a little over-the-counter hydrocortisone cream to relieve the inflammation.
can the application of the product "biofreeze" to the penis cause long term damage? . during a sexual encounter the pain relieving gel was applied to my penis and it has been a few day since the experience and the pain still persists.
