I'm not going to pick one because I'm not that picky, for me it's more to do with size then the look of it. After all, when I'm 'using' it, I don't really see it
I like realistic, and I like cool ridges and bumps. Smooth is fine, as long as the texture isn't completely slick. If it's just slick it's boring and does nothing for me.
I used to be uncomfortable with the thought of really realistic dildos, but have been warming up to it lately. I really like nice defined heads on my toys. I think something semi-realistic (like, say, the Vamp) is the best for me.
I like a certain amount of texture, and the realistic ones are nice too. But I mostly worry about what it feels like and whether or not it gets the job done!
For me, well done realistic toys are very appealing in looks but a toy that poorly mimics the look of the real thing is not. I prefer an unrealistic look to a toy over a shoddily colored realistic toy. Toys of a solid color that have never been skin tones are disturbing.
Early on we avoided realistic toys but as we upgraded our collection from plastic and jelly - we often found the realistic ones had many of the features we were looking for. We started buying VixSkin and in our book there is nothing more realistic.
I want it to be realistic in the way that the dildo is shaped like a penis but you can keep all of those ridges and veins. They irritate my vag and I get sore much more quickly.
