Tips for how to best use our new Aneros?

My SO and I have been getting fairly kinky and he started to show interest in toys for his prostate. We looked around online, read reviews, etc. we ordered an Aneros Helix and used it last night.

He said it didn’t make him cum and harder, and it didn’t even feel that different, it just made him cum really fast. Like we got it in, I went down the on him for about a minute and he came. He can normally last an hour or more.

Any tips on how he can slow down the process and get that full-body orgasm we were hoping for? He seemed kind of disappointed.
