Am I using my toy the right way?…

I am a beginner I’d say, since I’ve only been working on prostate play more and more the past few months, and I initally only had the original aneros prostate stimulator, but now I have a few others which are the Progasm and the MGX Syn Trident and also a Njoy Pure wand. Lately I’ve been using the Progasm because it felt better and this is what I basically do.

I lay on my bed, start to watch some videos and wait like 5 minutes until I’m getting aroused and then start to lube up and work the Progasm in and once it’s in just let it settle and lay back on my bed. Once it’s settled in, I go back to stroking every now and then keep myself semi-hard to nearly fully hard. This is the part I don’t know if I’m doing it right or not..but I would take a deep breath and pull the toy in, and like clench every few seconds in between for as long as I can go before exhaling and holding there, resting and repeating that process. I don’t know if I’m suppose to be doing that or not. I do notice though I start pre-cumming alot as I’m stroking and doing those deep inhales, pulling the toy in as I’m doing it, but I don’t know if it’s from that or if its from me just being aroused.
