Let me begin by saying I really enjoy anal, but would still consider myself new to it. I just received this plug today and it feels fabulous! I was concerned since it had the world “large” in the title, but it is just right! It is made of a high quality silicone, is very smooth, and the base is quite flat and curved, making it easy to wear during the day…sitting, walking around, I was even able to take a nap in it. I would recommend it to anyone wanting a good quality, comfy plug
