(30M) Used aneros for the 1st time and didn’t have any orgasm. Any suggestions?

I’m a 30 year old gay man and I used an ameros for the 1st time. I just tried anal sex one time, but it went horrible because at that time I didn’t know about how to clean my ass right, so I never tried again. Today I used my aneros Progasm, which is recommended for intermediate users, however it wasn’t a problem for me to insert it and leave it in my ass. I was horny, I watched some porn and then inserted my progasm. I did some contractions so it stimulates my prostate, but it wasn’t as pleasant as I expected. So I worked it manually and I know I was hitting the right spot because my penis was getting really wet. I played with the prograsm for more than an hour, but however I didn’t reach the called “super o”, so then I just masturbated as usual. Any suggestions on how to use it? Thanks in advance.
