Progress and a new toy

So i bought a new toy recently a suction cup 5inch dildo, just to see how things went with that. (also i wonder if using this is going to effect the way aneros use may work/aneros devices may work, is it a good idea?)

As soon as its in it instantly makes precum, i get amazing feelings, super erections and then after a few minutes, the arousal vanishes and the prostate just sort of goes to 'sleep'

I realised that just now this reminds me of something else...something I've been saying for a long time on these very forums.... its exactly like my aneros sessions. its like after a while it stops working, sen when changing technique. Then a few mins later (perhaps 15-20) it sort of wakes up again and I'm horny.

Both the prostate AND the arousal.desire vanish and reappear together.

What is this? i know if i can get past this i can further my awesome journey and actually experience a dry orgasm, as it stands I'm just on the edge of discovering it! i never get enough time or things get 'too tight' with the swelling in there that it shuts down before things really hot up/ For example everyone here states as the session goes on the feelings intensify, for me it starts intense and begins to drop off into nothingness! total reverse!
