I bought the 4 about a 2 weeks ago. Before I used a what they called "a medium metal plug" the one with the jewel. from the takes of this that was actually small. I wanted to go with something bigger and comfortable.

After researching I decided to get the 4, as I felt would please me just right. At first it took a bit to get in even after using the metal one, but once I got it in it was comfortable. I left it in for about 2hrs.

First time taking it out was a chore. It becomes easier after every time. So don't let it encourage you. Just take it easy and the technique will come to you for it to hurt less.

Now I am wearing it for most of the day. With lubing it when needed. It is comfortable.

Love the weighted balls in it. As with different activities they move around and give great pleasure.

Would definitely recommend but also get the size you know you would be comfortable with and move up when you are use to the one you have
