I am too. It's always a risk, but when I find someone who accepts it, I feel such a rush and relief, when I meet someone curious or who is into it, I feel like I can tell them anything. I love my dogs and stallions and I'd never hurt them. I always make sure they're in the mood to be intimate and if they're not, I have dildos and the internet!
I do think more people would be open to certain things if society had not conditioned them to have a subconcious response of what is expected of the "norm". I do get some of the objections though and there are things I do think should never be done, both on a personal taste level and morality one.
Like I said, no simple solution to it.
