Always a HFWO

Hello everyone, relatively new user here (couple months) with some success, but I always seem to end up ending a session with a HFWO. I have the MGX Trident. There has been one instance where I feel like I made great progress, I was listening to the kinkyshibby audio for aneros (I can link below if needed, unsure how to link in post on mobile) after reading some other comments recommending it. Got about 50 minutes in and my entire body started to shake and I got pins and needles all over. Started to orgasm hard, definitely felt more than a normal orgasm, and it started out with me not cumming, but eventually after most of the pumps some cum did come out and I had to deal with the refractory period. It seems that every session I have I end up with a HFWO, and a normal refractory period. Does anyone else experience this and does anyone know of any tips to lead towards a HFO and Super-O? Thanks for your time!
