I'm a guy and i never shaved or trimmed my armpit or groin area ever but now I think i will have to do it because everyone says it looks better if you do. My question is whats the difference between shaving and trimming? Also, what is the best product to get the job done? I have a philips phillshave that i use to shave my mustache. I know it would be disgusting to use that same thing to shave my pubic area and armpits as well so what would be the product you recommend? I know it would be a lot cleaner when armpits have absolutely no hair but would that be the same for the pubic area?
