I was wondering if you guys find that there is a difference between prostate and anal orgasms? A couple of weeks ago, I placed my wife’s suction cup dildo on the bathroom floor and rode it for a while until I came without touching my cock. This was the first time I ever came like that and what really helped was imagining being submissive to my wife having a cock. It felt really intense and the volume of semen was really large. Not sure if it was an anal or prostate orgasm?
You don't say what you mean by "rode it." I hope you realize that you can stimulate your prostate, and some doctors do manual prostate examinations, without penetrating the rectum. There's a front-door approach to the prostate and a back-door approach to the prostate. Without knowing what you mean by "rode it," I can't tell what part(s) of your body you were stimulating and how. Also, because soft tissue is connected and nerve sensations (both pleasure and pain) radiate, orgasm is orgasm. You orgasmed with ejaculation. Specifying that an experience was a "prostate orgasm" or an "anal orgasm" demonstrates a misunderstanding of orgasm and anatomy. You may be able to say that your orgasm was triggered by anal stimulation, but it isn't clear from your posting that there was anal stimulation. You may be able to say that your orgasm was triggered by prostate stimulation, but it isn't clear from your posting that there was any prostate stimulation. It would help in your quest for knowledge if you looked at some illustrations or diagrams of male anatomy in order for you to determine exactly where you applied pressure.
To me anal sex is prostate you can focus on only the prostate but (in my opinion) all anal sex stimulates the prostate creating the orgasm.
