Yes, it’s recommended. My doll saved my sex life. Let me explain. I was having some problems with a medication I was taking. All of a sudden, I was having a hard time getting my little warrior to stand upright, you know? I was really worried, so I bought this doll because she turned me on, and when I looked at her website, I got an erection, which I took as a good sign. Now I have a “real” girlfriend who is thankful that this doll saved my sex life.
