I get a random erection after petting cats/dogs...?
Before you think I'm some sort of freak: I have no, nor have I ever had sexual attraction to animals, trust me.
However, I've noticed that whenever a cat or a dog is in my lap, I get an erection. I can kind of understand that, but whenever I pet my cat and he starts purring, I get a random and uncalled for erection. It used to happen with dogs too, but not so much anymore. This also happens when my cat rubs against my legs. I have no sexual attraction to animals, so why does this happen? This only happens when I make physical contact with my cat or sometimes a dog. Other than that, I NEVER get an erection from animals.
