The Titanmen Man Tube is incredibly soft, both inside and out, made of a material known as Ultra-Realistic 3.0 or UR3 (NOTE: UR3 is a very porous material and should not be shared without a condom or knowledge of your partner's STI status). The inside is lined with soft textured bumps that tug with every thrust. It is also quite tight and a liberal amount of lube is recommended but that's part of the fun of simulated anal sex. However I found it to have a fairly strong plastic like (but not necessarily offensive or overwhelming) smell that will cover an area with a radius of about 4 feet and will linger on your skin for 15 minutes or so. The material itself is very floppy and as a result using two hands to get things started is much more efficient than trying with only one. This toy will also collect dust if it comes into contact with say, your carpet, so be sure to make an effort to keep it somewhere where it will be protected.
The design of this toy isn't exactly the most appealing thing to look at but at least I can say that it somewhat has an anus opening which gives it some, though minimal, realism. The shape is designed to be handheld so it has two bulges to make it easier to keep a hold of, especially if your hands are covered in lube. The size of this tube is 8 inches which is nice because it will give the average man some extra room to work with so most men will have no problem with this. I don't see a reason why even someone with a large cock would have a problem with it.
I do have somewhat of a concern about the durability of the material though UR3 seems to be known as a fairly durable material so it's my guess that with proper care this toy should take a few solid years of pounding before anything happens. This toy isn't the most discreet as it is large, but its purpose isn't as obvious as a fleshlight or something similar. Due to this, it isn't recommended for travel.
This is cleaned by washing it with soap and water, do not use harsh chemicals, alcohol included. Corn starch can be applied to the surface to keep it soft and help keep it from deteriorating. After washing out the toy you may choose to turn it inside out to dry, I however have found it easiest to turn approximately half of it inside out dry with a towel, and repeat for the other side then allow it to sit for a while to finish air drying. When storing this toy it is best to keep it somewhere where it won't get dusty such as a rubbermaid box. As far as the use of lubes go, this toy is latex free so a silicone lube can be used, and of course water based lube may be used as well, I prefer a silicone-water hybrid as it isn't as sticky as water or as greasy as silicone but can still be reactivated with water. Oil based lubricants are not recommended as they can decrease the longevity of the product.
The Titanmen Man Tube has proven itself to me that it will make your orgasms harder and more intense especially when compared to a traditional toy-free solo session. As you reach climax you will almost certainly feel the bumpy texture of the interior pull at your cock and as you climax you will find yourself grabbing the toy in an attempt to maintain control.
