First session with good progress, what’s next? 3

I got myself an aneros helix trident (plastic) and used it for the first time today. It’s my first sex toy let alone a prostate toy, so I wasn’t sure what to expect. I got in a shower tub, turned on an audio from r/gonewildaudio, lubed the toy up and put it inside me.

Nothing really happened for the first 20 minutes or so as I was just trying to relax and arouse myself. I slowly held the aneros with my PC muscle and let it go, repeating that slowly while gently thrusting my hip. Some time past, I felt like I leaked a drop or two of precum. I got distracted by the surprise of it so the leaking stopped quicky, unfortunately. Some time later, every time I clenched on the aneros my lower body started shaking like a maniac. And then, you know when you slept on one of your arms and afterwards it feels like your arm is numb and it feels like there’s sparks flowing through it? That happened to my whole body. My body didn’t exactly get sensitive, contrary to what I’ve read, just that sensation. I also felt like my bladder was full and I had to pee, but everytime I tried to pee I couldn’t, as if there was a wall blocking it even though I wasn’t hard (why did that happen?).

Spit as lube?

I just bought a helix trident and I’m planning to use it with a cock ring for my first ever prostate experience. I don’t have any lube and I can’t get one for personal issues; can I still use spit as lube? How do I apply it to the trident? How to I get my hole lubed effectively? Can I also use conditioner or lotion (Cetaphil sensitive skin) as lube as well?

Edit: just heard about cooking oil as alternatives; do these work?
