Well, Im currently zoo exclusive but Im not opposed to that changing in the future.
I was in a 5 year long relationship that should have been a 6 month relationship. It came with arguing, fighting, breaking up, getting back together, emotional abuse, and the PTSD to follow it. Going into it I had a lot of romantic innocence, coming out of it I became distrustful of other people. This chick was textbook definition of daddy issues, and he made sure to drive a wedge in our relationship as often as possible to boot.
Point being, I swore off relationships for some time and indulged in the furthest depths of perverted fantasies, let the sexual beast loose a bit. This translated well into my zoo desires when I began dog sitting for a friend with an intact female.
My parents had dogs growing up, but they were outside dogs. I absolutely ABHOR the idea of "outside" dogs now that I know better. Its a god damn family member dammit! To isolate a pack animal like that and subject it to the shifting weather makes my blood boil (end rant.)
That being said, this was the first dog that I got to know their personality and she was also my first real sexual experience. I fell in love with her and she was always so happy to see me. She passed away early at 5 years old and a part of me felt broken.
It was after that when I decided to commit to having my own dog, best decision Ive ever made. Shes a beautiful pit/boxer mix with a unique coloring that gets compliments all the time, super smart, super sweet, a nice size around 70 pounds, and loves our play time together.
Sex aside, having that sense of companionship and caring filled that hole of desire and love that all humans need. However, I say Im not opposed to a future outside of this zoo life because there is still a certain sense of emotional intimacy, comfort, intellectual connection, and support that you can't get from an animal.
Sex and companionship can be had with animals, but a mental, emotional, and spiritual bond can only be had with other humans, and I do miss that.
