no.
however it may sting when soap makes contact with the very tip of your snake/inside the urethra, but that is normal because of the pH differences and because you're richard wasn't really made to have liquids put inside it, only interjected out.
unless you're putting gross, infectious liquids in your richard hole you're fine.
nor will it lead to infertile sperm. so you're fine on reproduction.
i know this because i wash my richard in the shower. 9/10 times soap gets in and stings like a motherforgeter.
