Immediately after trimming pubic hair and washing you will want to apply an aftershave or moisturizer of some sort. Remember it should be alcohol and perfume free, I’ve used one with alcohol in before and I can tell you now that it wasn’t a nice experience!
I have friends that swear by Coochy After Shave Protection Mist but my preference, particularly when trimming rather than shaving, is for Coochy Protection Powder. Applying one of these immediately after trimming will help to reduce itching, irritation, chafing and will leave a protective barrier on your skin.
Daily use can also help to reduce the discomfort caused by stubble between trimming.
