Having trouble not cumming from aneros

I’ve been making great progress over the past few months. First it started with mildly pleasant sensations, then aneros-enhanced penile orgasms, and finally I felt like I had a breakthrough last week. I was literally screaming at the top of my lungs, orgasming for about 30 seconds straight while I thrusted uncontrollably as my eupho fucked me. But it seemed like I got there pretty quick and I came (an unusually large amount of cum fwiw), so I couldn’t really get back there again like everyone else describes their hours long sessions. Any tips to experience the orgasm but not cum?
