I've heard of many people (males) experiencing anal orgasms through just toying, but no matter how hard I try I just can't get it. I've tried many different toys and methods but for some reason I still have trouble. I desperately want to experience it and so I am asking the pros here. Is there ANY toy BD or otherwise, that is a surefire toy to achieve this with?

No, there's no surefire toy that works for everyone. What one prostate sees stars over is gonna do nothing for the next one.

That said, if you want to work towards this, step one is figuring out your prostate, where it is and what it likes. Seems like you've been working on this, but keep at it. Play with fingers, toys, angles etc until you can identify what works for you. You may need a curve, a blunt tip, girth, a targeted toy to sit on and rock against, a very firm toy, a squishy toy that doesn't overstimulate, etc etc. You might need to be on your back, sitting, standing using a toy on a shower wall, whatever else.

Personal recs (from someone without a prostate, so take them with a hefty grain of salt) would be to consider if you like vibrations, and if you do look at something like the Rosa Rouge or the Prism VII Rouge equivalent. The warming really helps with relaxation and sensation.

If you're OK with smaller plug style toys and learning to use something new, I'd look at Aneros, who make very specialised prostate massagers. They're very firm, though. Most stuff marketed for prostate massage will be, since firm pressure works for many people.

Bad Dragon have a lot of good choices if you want something softer. I'd consider Flint for girth and texture, Nox for the curve and spot targeting head, Echo for its curve too, but just about any of them could conceivably hit the prostate.

I have tried Nox, and I have to say I love him, yet I wish I got him in a higher firmness. I'm actually thinking vibration might be the best way to go, and those aneros toys look like they might be the best route.

Sounds good! If their vibrator doesn't work for you, I'd look a Tango and slotting that into similar toys with a bullet slot like the Tantus P-Spot. I may be wrong and the Aneros line could fit the Tango, which is the most powerful bullet vibe I know of, but I don't think it does.

After some pointers from a couple of guys on the forum i found that i was not letting myself experience an anal o. You have to give into the moment and think of nothing but the pleasure you are receiving. I always worried about my neighbors hearing and thought about that more than what i was feeling. After learning to let go, relax, and have no expectations i finally had one. Just be patient, have fun, and don't care. The toy that did it for me was my large Clayton. I like texture and i found the angle to ride it that best stimulates me.
