Background - I have the Tantus Abomb and Severin Large and was looking for a bigger (girth) toy. Bought the SBM a month ago.

Material - the SBM made out of smooth silicone. It has no smell at all. It’s smooth and not harmful for your health like other plastic toys can be. The silicone is firmer and less compressible than the Tantus Abomb and Severin Large.

Shape - the SBM is designed to hit the P-spot. It's girth 2 1/2" (thus NOT 2 1/4" as in the description, I've measured it!) is somewhat the same as the Tantus Abomb and the Severin Large (app. 2 3/8" - 2 1/2").

Experiences - First of all, you need a smaller toy to begin with. The SBM goes up pretty fast to the maximum girth. I used The Tantus Severin Large to begin with. Once I manage to get the Severin Large in, I went to the SBM. The SBM stretches me a little bit more despite almost the same girth as the Severin, this is due to that the Severin is a little bit more compressible than the SBM, so it went in pretty easy.

However, the filling of the SBM is just way more than the Severin. It's just so much that in the beginning it might be a little bit uncomfortable. Despite this, after a couple of tries, it will get better. But this is when I'm laying on bed. Sitting with the SBM in will just put too much pressure and keeps it uncomfortable.

About the shape, when you insert the SBM right or try to rotate it a little bit once its in, you will feel a little bit more pressure on the P-spot. Nonetheless, with toys in the 2"+ diameter-segment, how can you not have pressure there? I found out that I got more aroused with the Tanus Abomb inserted than the SBM, probably because the Abomb reaches its max girth earlier than the SBM. The base of the Tantus Abomb and Severin is also better designed and fits better between your ass-cheeks compared to the SBM.

I have had the SBM for a month now and came to a surprisingly good feature of this butt plug:

I've never experimented with heating-up a toy, until now. I had boiled some water half an hour ago, put the SBM in for 20 minutes, and actually right now plugged it in: WOW, it feels much better!

Probably because of the large silicone mass, it absorbs a lot of heat and stays warm for a while. So when it feels uncomfortable, just heat it up!

Furthermore, I wrote that for instance sitting with the SBM would create just too much pressure which feels uncomfortable. Well, I have to take back those words because the last couple of times I tried to extend plugging time a little longer with sitting and feels much comfortable than in the beginning. Especially sitting with the SBM is just a roller-coaster-ride, so aroused and I got an erection it was unbelievable. I just came automatically and without any physical contact (which I don't have with other big plugs). I’m actually more and more eager to use it. So when it feels uncomfortable, just be patient.
