The Big Guy is 100% silicone. The texture is very smooth. It is certainly not a matte texture like some silicone manufacturers tend to produce, but it still requires some lubricant to keep things moving. It is more pliable than glass or metal, of course, so it may be the perfect alternative if you don't like the rigidity of those materials. Other than the bulge, the material is essentially featureless until you get to the base, which has DOC JOHNSON impressed into it. This is not noticeable during wear, but it is there. The silicone color is a marbled gray which is handsome, in my opinion. Not as "bad boy" as black, but more subdued than a red or pink. A very nice presentation, overall.
The Big Guy starts out with a rounded shaft with a diameter of 1 1/2", which then increases to 2" about 2/3 of the way down and then drops back to a neck about 1 5/8", before going to a base that keeps it from slipping inside. Having the smaller diameters before and after the peak gives one the ability to get it inside and relax on the start of the shaft before going for the full stretch, and then having a nice neck to relax back on to. The neck isn't too long, so the plug doesn't slide out very much while being worn. The shape is pretty unique among butt plugs but really seems to function well.
How the Big Guy performs for you is going to depend a lot on your anal play experience. If you are used to accepting large objects, then he should be no problem, but if you are used to smaller items, then the Big Guy will present more of a challenge. The Big Guy certainly was a challenge for me, but I haven't played with a 2" diameter plug in quite some time, so I was a little rusty. The nice thing is that I don't really need a separate warm up toy as I can take 1 1/2" pretty easily. The first part of the shaft then acts as its own warm up and allows you to work toward the 2" bulge at your own pace, to some degree. Once lubed up, the Big Guy doesn't stay in at the smaller starting diameter unless it is held, but you can definitely use that smaller diameter to remain staged as you slowly work toward the larger diameter. It ends up working very well for me.
100% silicone is a great material for anal toys, as it is non-porous and can be completely sterilized. Regular cleaning can be accomplished with soap and hot water, but deeper cleaning options include wiping with a 10% bleach solution, boiling for 3 minutes, or throwing it in the top rack of your dishwasher without soap. Once it is clean and dry, storage is simple; just keep it from touching other silicone based toys. Water or oil based lubes are fine to use with 100% silicone. Silicone lubes may degrade the material, but if you really want to, spot test somewhere on the base of the toy with the silicone lube, as an immediate reaction will result if the lube is incompatible. The glossy finish of this toy makes a silicone lube reaction very obvious.
Doc Johnson chose to package the Big Guy in a clam shell container meant for hanging. There is a cardboard insert behind the plug which lets you know that it is made out of premium silicone. The Big Guy is clearly visible, so you certainly know what you are getting. There are no pictures of men or women on the packaging, however, so I would consider it to be discreet. I suppose the packaging could be kept for storage as long as you don't mind the extra space it takes up. I keep mine in a muslin bag and recycle the packaging.
