HI My steady girlfriend and I enjoy foreplay very much and lately we have been working it up in the bathroom. She pulls my cock out of my pants at the sink and lathers it up with soap and washes me thoroughly. I return the favor by showering with her and washing her parts as well. The problem is that many types of soap are irritating to mucous membranes. That is, they sting your urethra. Does anybody here know of a soap that does not do that?
