A bit frustrated: Can’t get beyond the “tingling stage”

I’ve been using a Progasm Jr and recently a Helix Syn for approx. 2 years now. Nothing much happened until some months ago where I started to get P-waves and tingles pretty much every time I use the toy. There where several instances where I got intense shivers, heart racing and the feeling of an immense pleasure incoming, so intense it made me even afraid. When it happened for the first time, my prostate tingled for two days which made me pretty anxious.

Also, I’m so far that I can basically alway cause P-Waves/tingles just with thinking about it, like a mental switch, and it’s almost as strong as with the toy in.

But that’s it – I never feel I can get beyond this stage. Is it the toy? I feel that they Syn works better for me than the Progasm Jr, so I thought about maybe getting another model, but there seems to be no consensus on which one.

Something I have also tried is stimulating the toy from the outside with a Magic Wand. It feels amazing and very tingly, but it’s just “constant pleasure”, but not like it would lead to climax. I can control both muscles independently, but “do nothing” worked best for me so far.
