What am I doing wrong?

I purchased the Aneros Helix Sun Trident almost 10yrs ago and I’ve tried it maybe a total of 15 times always with high hopes and I’ve gotten minimal results almost everytime. I’ve relaxed and given myself space and time, used my muscles to work it back n forth, kept it in for about an Hr., even used it during piv sex and still nothing seems to give me anything mind blowing. I’ll even add when I stimulate my perineum I get an amazing result maybe not mind blowing but on the cusps of it. I’ve even tried prostate massages with partners finger and that feels better than the aneros but still not as powerful as the perineum massage and not mind blowing.

I do orgasm from masturbation and having something inserted gives a slight bit of pressure which feels better but I feel like I’m missing out on something with this. Does it sound like I just need to try something bigger or is my technique wrong?
