Sometimes but not always. A lot has to do with the material and or design. For instance, I have a mouth and vagina Fleshlight. Both are made with the same color SuperSkin, they both have the same tightness. On the other hand, I also have a clear mouth Fleshlight and it feels tighter.

Most of the time the ass toys are made with a smaller entrance so there is some difference in feel but not always. You would have to have two toys made by the same company, the same shape/size to really be able to tell the difference.

I would say for the most part it is a visual deal.
