6 months in, I need some tips!

Hey all, I'm new to this forum as a member, but I have been an anonymous reader ever since I purchased my MGX. I finally decided to join, as everyone here is or was on the same journey that I'm on.

I just want to know if I'm on the right path here...

I tend to have 3+ sessions with my aneros a week. I find using a bit of vaseline and ID Glide as lube and lying on my back with feet flat is most effective. I'm at the point where I can feel strong buzzing from the inside (feels really good:D) after holding a constant light contraction. My cock gets rock hard and throbs away during this buzzing and I've noticed my balls move around a fair amount. I can feel a light pulsing in my butt. However, each time I find the pleasure builds up to a certain point and then dies. I can usually get the buzz back by adjusting my contraction, but only to end up losing it after some build up again. What am I doing wrong? Is the buzzing the right thing to be feeling? What are "involuntaries" supposed to feel like?

Also: I have tried using the aneros with my cock ring in hopes of helping me get to the super O faster. It always feels nice at first, but I find that the inner buzzing sensations I get from a session without the ring are stronger. It may be worth pointing out that my cock ring has a piece that applies pressure on the perenium. I have a feeling it may be interfering with the aneros's perenium pressure piece.
The cock ring can be used backwards as well, in which the extended part lifts the testicles instead of applying pressure to the perenium, but I haven't tried it this way with my MGX yet. Has anyone else found success in using a cock ring with their aneros?

Thanks for any help in advance.
