Assgasm from dildo?

I need some help clarifying what happened earlier. So I started a session with the progasm and went through my normal routine’s and had several good dry orgasms. After a while I took it out and went to try a new small to medium size realistic dildo I had just bought. I lubed up and started playing and it felt really good. After a while I switched positions to on my knees and started thrusting pretty fast. As I did I clenched down a little bit on my prostate and then felt everything inside start swelling up. I kept thrusting even though it wasn’t going as deep and all of a sudden I started shaking and getting spasms from my thighs in to my stomach. It felt like a really large dry orgasm. As it subsided I was shaking. Relaxed a little bit and then went out it again and as I clinched I felt the same thing happened. It happened three times and was really intense. As it happened everything inside started to swell up and it was harder to get the dildo in and out but felt so good. Was this an assgasm or a dry orgasm from the dildo?

I still feel so sensitive inside. It is great. For years I have been trying to get some kind of orgasm from a dildo and it never happened. I thought it wasn’t possible but this was fantastic.
