Is this my prostate?

I am a Beginner to all of this. So I’ve tried a few times and haven really ever achieved what I wanted out of it. Was feeling around in there to get a sense of where it is at and a came across this sort of fat bulge in there. It’s quite large and feels like it almost blocks off anything from going any further in.

Or am I completely off and it might be something different like a hemeroid?

need some help/tips.

ok so i bought a loki wave. i started off with smaller toys before that have slipped in rather easy. i can get it about halfway in and its just feels like its stuck there after. what should i do? should i push a little harder? im scared i might hurt something down there. i used plenty of lube. not sure sure if this happens to other but i was bleeding a bit after trying to get it up there. not a lot of blood just tiny spot on toilet paper. is that normal?

separate question how exactly do i know where my prostate is. it all feels the same in there to me. this toy is pretty big how do i know if ive reached the spot? im 5’11 will i be able to get the whole thing in to take advantage of the 2nd vibrator.

as you can tell im still pretty new to this all. havent really been able to find my zone yet. any advice helps really. sorry for the long post.
