Smooth probes are columns with a spade tip. In that, they can serve as regular bangers. The top spade makes them more useful for prostate stimulation than is the case for columns or bullets, since the former are better suited to uniform dilation, while the latter have a tip that is not tapered enough. While initially I had some reservations about the inspiration for these tools, I ultimately stopped caring, as I'm not willing to forego the backdoor pleasure associated with using probes, be they smooth or textured. The Colossus is a fairly smooth, uniform dong with a 73 mm top spade of minimal texture and a single fold. Past that, the shaft is relatively smooth all the way down. All my toys are for the backdoor, and thus since I prefer to use hand-operated bangers rather than sit-down riders, I sawed off the appendages at the bottom, as well as quite a large portion of the bottom shaft. The resulting banger is similar to theImmense Ivan , but much heavier, almost too heavy for hand use while standing up. The secondary type of usage is that of a column dilator. Entry: ------------------ The top spade would have been fairly easy to insert relative to other bangers of that girth, but the noticeable fold forces one to be very careful. This 8 mm 'step' always managed to deprive me of oxygen for a while during the first several insertions. The breathlessness was so intense that I found myself extracting the banger almost as soon as I slid down onto the shaft. Said shaft never falls below 71 mm in diameter, and therefore offers no respite after the step, which is nonuniform, and reaches as far as 69 mm down. Well then, I just had to get used to it. After the first trial attempts, I sawed off the appendages, and shortened the toy to 290 mm, with some 210 mm of insertable length left, as I prefer to use the Colossus as a handheld banger. That done, I washed it, left it to air out, and took myBed Knob Buddy Small dilator from TSX for a walk, for the first time. That is one tough dilation cork, always pressing on the second outer sphincter from the inside. This exercise allowed me to take the Colossus during the second session later in the day -- take it in and *stay* there. Easily done after the Knob. Since then, I have enjoyed the Colossus many times, and even with the 'step' taken into account, I now ram the Colossus inside in a single push. Play: ------------------ It took me five insertions to achieve enough proficiency with the Colossus in order to become comfortable with the level of dilation the shaft provides. Having reached that level, and having amputated the bottom, I now use the Colossus as a fast banger. It is heavy, very heavy, even after the amputation. Slightly textured, it stimulates the outer sphincter much more strongly than theImmense banger . The experience of the Colossus moving at speed and ramming at my prostate is very, very intense, as delicious as theB-10 Torpedo from Doc Johnson, bringing me close to backdoor release, albeit with extra sphincter stimulation. highly recommended, even if other insertors would prefer to preserve the fet aspect of this toy as shipped, and choose not to cut the bottom parts off.
