I very much enjoy affection from animals, within reason. An English Mastiff pinning me to ground to coat my face with slobber is another story.
From humans... I'm very leery of physical contact and even close presence is uncomfortable. I'd like to think that someone I'm attracted to that wouldn't happen but I don't honestly know. With family and whatnot, I definitely prefer to not be touched, so I'm not sure about a lover either. But still, there's a hope that I could get past that.
