They sell a lot of non human looking dildos

It seems that they sell a lot of dildos that look more like Spot's and Rovers than Bill or Doug's dicks.. So I wonder how common this fantasy is, and how many couples share the turn on thinking about it. Most of us have played the dildo gang bang where we use a section of sizes and shapes of dicks on our wives. Some of ours are young lad sized, so maybe Rusty Lab size is also sort of taboo but allowed in sex play. I have talked to women that have done more than fantasize with their pets, and they reported very enjoyable experiences. The curiosity to experience a different dick includes some very different dicks. I'm wondering what other couples think about this.
