How, yes, no.

Cons:
Even if you don’t see any cuts, shaving and waxing can cause “microtears,” or tiny cuts in the skin. These are entry points for bacteria and viruses to get into your body—which include STIs. Human papillomavirus (HPV), herpes, and syphilis can be transmitted through sexual skin to skin contact, and having open cuts or sores increases the chances that you may catch them.
Pros:
Plus, your pubic hair acts as a sort of cushion, protecting the sensitive skin around your genitals from too much friction during sex. When you shave it off, it’s more likely that friction during sex will create those same microtears that shaving does. It also traps bacteria.
