Feeling a buildup, not sure how to proceed.

Hello! I appreciate your time and reading this.

So, recently I have been feeling some kind of build up and I can feel it hitting my prostate and if I relax my muscles, it gets sucked up.

However, I am not sure what do with this feeling. It feels great, but get rather lost on how to proceed.

I try to go with the flow and just do what feels good, but feel like I am missing something to do when I get to this point.

Advise: Seem to lose sensation after 20 minutes or so, I take it out and put it back and little by little it goes away.

So, when I start my sessions, I can feel it make contact and have been getting better about relaxing muscles, contracting, and just going with the flow of the feelings and building on what I feel.

I have seemed to reach an area where after 20 minutes, it’s like I lose all sensation and so I take it out and put it back and then I feel something, but the sensation goes away after a few minutes.

I THINK it has to do with my brain and not paying attention and my mind drifting, not 100% sure. I am a beginner and just wanted some advise. I suppose at a certain point, we all expiernced this, having a hard time 100% focusing on the sensation vs mind drifting

Best Lube For Aneros Syn?

Hello, I am currently using this lube: https://www.amazon.com/dp/B075SN1MY9?psc=1&ref=ppx_yo2ov_dt_b_product_details

I find that it does not last very long and I feel like I constantly have to take my aneros out and re-apply lube.

While this may be off topic of the lube choice, I feel like after inserting, I get sensations for about 10 minutes and then loose all feeling, not sure if this is due to the lube drying out and the toy not moving or if it is just me.
