Is it normal to get so much pleasure from having anal sex beformed?

Many years ago I learned that I love to have orgasms. I'm a normal man. I have great sex and cum from jr. However, nothing can touch the intense pleasure and orgasms I have had from my bum. My lover she wanted to try a double dildo on me and I agreed. She was slow and gentle and before long the whole dilo was sliding in and out of my bum. The intense pleasure made me cum so many times and so much cum cam from my bum it was amazing. We talked about it and it gave her orgams giving me orgasms that way. The cum fluid she said is as much as her peach produces. We both think its great and I let me self open any time for her. I wonder if they make a toy that shoots "fake cum" in me to feel if that is as much pleasure as me cumming in her?
