What is going on

Hello. Let me start by saying that I have been trying prostate play with the aneros for about 2 years now. I have had the helix classic, I now own the helyx syn, the peridise and the progasm ice. I have not really had the super o or earth shaking orgasm everyone speaks of. It has felt ok at times, it has felt good at times even great at times. Never a hands free orgasm. Well last night I had a session that was a little different. It lasted a few hours. I started with my helix syn was super horny felt small pleasure waves pass through me on and off. But was not really getting to the next level. So I moved on to the progasm. Things did heat up a bit. It felt really good. I love the full feeling of the progasm. So to not make this long and drawn out. I was feeling amazing but not wow amazing. I wanted to cum so bad or to at least just have some kinda jump to a level I have never been. I just couldn’t quite get there. I was totally relaxed and in the moment of pleasure. So I advanced to my wife g spot vibrator. I get a really strong tickling on my prostate with that. Almost like I’m going to see but a little different. That feeling comes and goes. Mostly because to keep it I have to press harder. I’m afraid of doing damage so I have to just take it in 10 to 20 second bursts. Well last night I was trying to hold it there a little longer and with a little more pressure and also trying to slide it around at the same time. Well last night I was able for the first time to achevie something that I have never done before. I came every where but in actuality I came no where lol that sound s funny but I’ll will explain .
I got the I’m going to cum feeling followed by I’m going to pee feeling. I’m just lying there (Oh my preference for position is on back feet on ground knees up ). Loving this new feeling when all of a sudden after about maybe a no it’s or 2 of this feeling coming and going. I get really warm around the base of my cock. I get that feeling that I’m going to cum. you know feeling your thick cum start to pass on its journey through your pipes to get out. But almost at the point of when it would fly free it changed to that lighter feeling of just taking a good piss. Like what was coming out was more lighter more fluid like substance. I take a look down at my cock that feeling like it is just gushing something all over the place like a fire hose. But I only see a little dribble of white milky cum and a little trail of clear fluid. Well from the feeling I should have been soaking wet. But from what was there. There was nothing. After that passed I had to stop. I wanted to keep going but I needed my session. So my question is what was this. Has anyone had this feeling. I was completely flaccid as I usually am during my sessions. I sometimes get hard on and off. But 80% of the time I’m flaccid. Is this feeling the true start of what’s to come and should I push and try to power through it and keep going next time. Also is there any tips or tricks or other units that one would suggest that work better than what I have. I usually use about 30 mls of astroglide (water based) if I’m using the helix syn and 30 mils of astroglide ( silicone based) if I’m using the peridise or my orgasm ice. Is this enough lube. Also another thing I have noticed that happens is sometimes my ass gets that feeling that I have to shit so bad it contracts so hard almost to hold it in. But usually my ass will squeeze out alot of the lube. With the toy staying in me a few time it has pushed of the toy. So am I doing any thing wrong in any area are these all normal Things. Any feed back would be great.
