are you talking about the difference between the purple one and the green one?

I would NOT recommend this product for anal play, but that is just my opinion. The base is not flared enough for my comfort level. If you wanted to stick low cost and with Doc Johnson, I'd suggest this one instead. The base is a bit more differentiated for the rest of it.

good luck!

I agree with Mr. Sauce. Also, it would be best to go with a non-porous material like silicone.

Some cheap ones are:

Hm, well I'm actually looking for a more penis-shaped dildo.
Smooth like this one, but still a bit of texture so it's not one boring slide fest, you know.
Also, the dimensions are nice, I can't take too much, but too little is of course not interesting either.
Cause I'm looking for a bit more of... action... hands-free too.
So not just a plug to insert and leave there or something.
Which would you recommend instead of this one?

If your plug is staining it's because it's made from a porous material, meaning it has pores (like the ones on our skin, but much smaller) that absorb microbes. Examples of some of the more common porous materials used for sex toys are jelly and rubber. many toys are made from some variation of these two materials.

Because they are porous they will degrade much, much faster than other toys and can become very smelly and discolored. Some of these toys, particularly jelly and PVC toys can contain toxic materials including cadmium and lead. The sex toy industry is not yet a strictly regulated one like, for example, pharmaceuticals. Drugs have to go through examination and testing before they are released to consumers, but sex toys do not.

For this reason it is highly advised that if you must use a toy made from one of these materials that you use a condom or barrier of some kind. A condom will slow the build of bacteria in your toy, and it will also protect you from any toxins that could be leeched into your body during use.

The best bet, however, is to invest in a non-porous toy made from a material like pure silicone. Some "silicone" toy are made from blends and are therefore porous, so it's important to make sure the toy is mad completely from silicone. Other non-porous materials include Elastomed or even harder materials like steel or Acrylic. These toys tend to cost a little more money, but the good news is you won't have to constantly replace them like porous toys because they cannot absorb bacteria. They also do not contain toxins like other materials often do. If you take good care of a toy made from these materials, they can last forever so you actually save money in the long run!

Hope that helps!

I'm not sure about the Throb. The material and base are good, but I discourage people just getting into anal play from getting heavily textured toys. Often when you're starting out you don't have the ability to relax your anus mastered yet, and a textured toy can be very irritating after a while if your anus is tense. A smooth toy is much better - look at the medium Silk link or a similar sized smooth toy.

thank you so much for the information and links

this was super helpful, thanks!
