For the most part I like a medium sized plug that just stays put so I can do other stuff. However, I have been lusting after the T-Rex by Tantus and I will need a good warm up plug for that. So I am now lusting after the Tantus Ringo as a very large plug. Talk about swallowing the spider to catch the fly.
I like enough to feel it and get a little stretch going on, but I don't want something that's a chore (or painful) to insert. I've been wanting to try an inflatable plug...easy to insert, but can be made thicker once it's all the way in.
