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.
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.
