Hello, I am a 23 years old male, and recently I was curious to find out about prostate orgasms so I looked it up on Google. I found out that the prostate is supposed to be between the base of the penis and the urethra, 2-3 inches inside and should feel like a walnut (?).
Lying on my back, I inserted a finger in my anus and I felt something oddly shaped but it wasn't towards my front side, but towards my back side. It is located around 2-3 inches inside if I am relaxed. It seems that when I relax the area this "thing" comes towards the outside. I am quite stressed about it and thus I am posting this question.
Should the inside of the rectum be empty, like a pipe? Is it normal to have such thing?
