Help!!

I masterbate everyday, I’m 15 I started when I was like 10 tbh I didn’t really know what I was doing back then it just felt good.. but anyways that’s not the point when I’m masterbating and you know that point you get too when it’s feels amazinggg. I just can’t seem to get past it after that I want to keep going and I want to orgasm but I just can’t and I don’t know what’s stopping me? Any advice?!
