The best use I found for the double bubble butt plug was to have it fully in my bum and receiving clitoral stimulation orally with a partner. Vaginal sex was really good too. It could also be used on a man while he is receiving a blowjob. I believe the main intention is for anal pleasure/training, which it is also good for.

It is made out of PVC and I can honestly say that this is the first PVC toy that I actually adore. It was kind of sticky to the skin, but after using water-based lube, it was no longer an issue. The only issue I had was that it kind of had a strong, sort of annoying, odor at first but then it went away after being cleaned a few times.

I feel that the design and shape are ideal. The anticipation between the small and large bulge is something out of this world. The main issue I had was that it was a little wide for me at first, but I grew to appreciate and love the feeling of being stretched and filled. I think it is a good size for average users in the anal department but not really a good suggestion for beginners.

I think the best feature is that it doesn't hurt after extensive use, which I have come to find with other butt plugs after being used for a long period of time--they tend to burn or cause discomfort. The base is also a good size and design.

Since it is made of PVC, this toy cannot be boiled. Instead, use warm water and liquid soap. I suggest getting a dollar bottle of Walmart hand-soap, which worked great for me.
