I'm sure i need your help 🙁

1) I always find it very dificult to have or to keep an erection the time i using toys and masturbate the same time...

This is quite normal and nothing to be concerned about. Fortunately you don't need an erection to experience prostate based orgasms.

2) i really need to put out my toy at the time of orgasm because its very dificult for my sperm to come out,i reading the majority of people who has using toys achived more volume of ejaculation fluids at the time of orgasm,why this is not working on me?

First, we need to clarify something, orgasms and ejaculations are not the same thing, you can orgasm without ejaculating, You can also ejaculate without orgasming though they most frequently accompany each other. Some men do experience some difficulty ejaculating whilst their Aneros is in situ, this may be due to individual variations in specific anatomy. If there is no pain/discomfort accompanying this phenomenon then there is probably no reason to be concerned.

3) since i started learning end experimenting on prostate orgasm secrets,i start using aneros helix trident,feeling great at the session,i keep my hands away from my dick and tryied to achive no hands orgasm,till now i only experienced some kind of perineum muscle contractions with a pleasure wave that is ending fast,i keep trying and i reach only at that point,i can not achieve an erection though and i can not go any fourther from that point,so after a few hours of trying i will end up masturbating as always

This issue goes back to your #1 question, erections are not necessary to achieve prostate based orgasms. If you can drop your expectations of maintaining an erection and equating ejaculation with orgasm your Aneros journey will become much more pleasurable as you start to enjoy the subtle nuances of your own body's ability to create an infinite range of pleasurable sensations.

Good Vibes to You !

I second @rumel , no erection is needed, in fact as time goes along I'm finding that during my sessions the frequency of spontaneous errections are reducing. Used to be every time I reached the point of orgasm I would grow so hard it became a pleasurable pain. Now I'm reaching the same heights with a shrinking member, I still do on occasion sport growth.

I have been experimenting lately with stimulation of an extremely small point on the coronal ridge. The sensations are much stronger soft inducing involuntary muscle spasms in the perineum inducing a prostate orgasm and diminish once hard till it gets to the point that ejaculation is inevitable but I never ejaculate. once at that point I go back soft but the sensations stay very high until I stop the stimulation.

thank you a lot guys for help,i will keep you informed
