Help

I’ve been experimenting with prostate play for almost a year now. I’m am unsure if I have ever had a real prostate orgasm before. Looking for some guidance. How long does it usually take to get there. Also what is the best way to locate it and what toys do you recommend? I have been using a curved stainless steel toy and like it but don’t feel like I have really found my prostate. How deep up there do I have to go? Anything helps me
