How to achieve an anal orgasm
Enema... duh!
Refrain from Cumming a few days.
Relax and tell yourself this is gonna feel good and be fun no matter what happens...
3a. Have some urine in your bladder so you have to pee just a little. (not necessary when you can already do this, but it helps the first few times).
Insert dildo as far as it goes and just hold it there for a full 1-2 minutes.
Start fucking your ass as you normally would for a few minutes.
Now angle that dong so it aims at your belly button and in past the prostate, on top of it actually, where the Seminal Vesicles are. (see illustrations).

When you tap that spot with the dong, it may feel like you have to pee, or it feels sort of cool/cold, it's a different feeling than when poking or rubbing the prostate.
Once you find the spot that makes you feel like you have to pee, especially when you hit it, stay there and keep that feeling going, even though the natural response is to relieve that feeling, or move around to avoid it, or minimize it, just feel it and feel it and feel it...
Thrust in quickly, whether a fast or slower rhythm is fine, try both, but when the dildo goes in, it should be fast, that will really help with making that, "have to pee" feeling.
Keep thrusting, the build up is slow and the pee feeling gets sort of uncomfortable, but don't stop it, it doesn't hurt.
At some point that pee feeling changes and the urge to stroke will be strong, just keep thrusting that dildo... The urge to quit, move to a different position, stroke it, of fuck yourself differently will get very strong, just keep thrusting...
When it feels like you don't have to pee anymore and transforms into the beginning of an orgasm, don't stop, it builds very slowly, just keep at it, cause, if you can stand it, it will build up intensity well past any penile orgasm you've had, maybe for minutes, but don't stop thrusting.
You may feel fluid moving through your dick unlike normal, that's the last thing and as you pump out that fluid, the real thing happens and probably so intense you'll cry out loud, or at least moan out loud.
If you are like me, this orgasm doesn't end abruptly like penile orgasms do, so, enjoy the minute after the peak also (still thrusting or not is just a preference at this point)
A few more notes for when a partner is trying to give you an anal O.
It almost feels like cold water in the area when it gets pounded.
have some piss in the bladder
If receiver is laying on their back, then the giver is between legs at same level, or a bit lower, so the thrusts are upward into the forward wall. When the receiver is laying on their back, giver lowers himself while inside the ass, causing cock tip to move up, if the receiver is on their belly, giver raises up, moving cock tip down. It can't be reached unless the cock is digging in behind the prostate, when you're there, you'll feel a certain sensation that I describe as feeling like cold water up there.
Giver's inward thrusts should be fast.
When you feel like you have to pee from his thrusts, that should be the beginning, forget what you are after and just let that feeling take you, don't guide it, don't judge it, don't analyze it at all, just feel it exactly how it feels now, not how you imagine it will feel better if you .............. yep, just let it happen and be patient, cuz, it can build and build for what seems forever...
