I just received this today. I had a little trouble fitting it in at first, but once I relaxed, it slipped right in. Ive got it in right now. Ill be able to keep it in for a long time. Once in, it stays put. It feels really great, especially when Im seated. Although its rubber, its soft, and you can squeeze it. If you like anal, youll love this. Strongly recommended!
