Thanks for your question and concern. As you may know, L Arginine is an amino acid. It is present in almost all forms of proteins and are commonly seen used for cardio vascular related treatments, developing lean muscles and to increase sexual health. It is a primary nitric oxide precursor. It is responsible for the relaxation of blood vessels and thereby increases blood circulation too. But there are no evidences found till now that there is a link between genital herpes outbreak and increasing sensation of clitoris using L Arginine. So, in my opinion, it can be used so that you can increase sensation of your clitoris. But it is advised to get prescribed for some alternative medicine also, from your gynec. Hope my answer helps. Good luck.
