Hi Pat. I noticed your thread, and I wanted to share my thoughts. I know this is long, but I think it will all apply and give you some perspective.
You've gotten great advice from the community, and I wanted to share with you a little, if that's ok.
Just to give you some background, my first sexual encounter ever was a pony mare that took my virginity (I am a guy... just want to make that clear, lol). I have always been attracted to horses- I have loved them all my life. Being somewhat isolated from girls my own age and being teased and picked on in school, I wasn't popular, and had little to no interaction with girls romantically, although I desperately desired a relationship with a girl. Being a horny teenager, I wanted sex like crazy, and the pony mare was happy to oblige. We had sex multiple times, but it was never able to develop past that as she didn't belong to me.
I was approached by a girl in high school that wanted to be with me, and I fell in love with her almost instantly. Sadly, this girl destroyed me by breaking up with me not long afterwards. I was crushed. We dated again for a short period of time, but she broke it off completely and I was left to nurse my broken heart for a long time (it took me a year to be able to hear a certain song without breaking down in tears).
My first marriage failed as a result of my spouse repeatedly cheating on me. We had both dogs and cats, and although I wasn't able to do anything sexually with the dogs (they were too small), I did let my dogs French kiss me. I enjoyed the feeling of their tongues in my mouth, and would have done more if I could have. Between my first and second marriages, I bought my first two horses. Other than masturbating while astride them, I was not sexually active with them.
I got married again, not learning my lesson from my first marriage. We had my two horses and we bought a third together. We ended up selling one of my two, and settled there for quite some time. We ended up having two boys together, and our marriage started eroding after the kids came along. As the marriage eroded, my previous sexuality started arising and I became interested in sex with horses again. The last years of our marriage were very unhappy, and sexuality between us was very limited. I turned to the horses for sexual release, and had many mare lovers, as well as a few geldings that enjoyed anal sex.
After we split, a Facebook friend of mine shared a post with me on the most lovely mare I've ever laid eyes on. A GORGEOUS chocolate colored mare with a beautiful long mane and thick full tail. I went down to meet her, and was smitten almost instantly. She was kind, affectionate, and exceedingly beautiful. I took her home and started working with her, and we built a beautiful, trusting relationship. I was fully active sexually with some of the mares I was around, and of course, my interest was on her, but I wanted to make sure we had built a good relationship together before I attempted anything with her.
We had just started being intimate when I met a woman and we started seeing each other. As I didn't want secrets in our relationship, I told her that I had been intimate with my mare, and she, of course, was shocked. She then got jealous and mistrusting of me and my mare (which I had stopped being intimate with because of my and my girlfriend's relationship) and we fought a lot because of her. I finally (and heartbreakingly) decided to sell my mare, as she was causing too many problems between us. I thought our relationship could go the distance, so I wanted all my effort and attention on it. That turned out to be one of the worst decisions I've ever made, as our relationship crumbled two years later.
Fortunately, the mare I sold ended up with one of my best friends, and after my gf and I split, she offered the mare back to me. I gladly accepted, and my mare has been back with me for over a year now.
That's my background- now here's the part I'm sharing with you because I'd like you to see how a relationship with your dog can develop. Over the past year, I have been developing the relationship with my mare. It's like we picked up right where we left off... like we were never apart. I've continued her training, as to my standard she was still green (still learning how to be ridden properly) when I got her back, and over the course of that time I have started being more aware of how SHE feels with what I'm doing with her. I have moved to positive reinforcement techniques for training, and that was the big jump-start to our current relationship.
A few months ago, a fellow zoophile started challenging me to see her in a different light. To spend more time with her, but not to train her, but just to be WITH her. To hear her, to understand what she might be saying to me, to listen to her. It didn't take long before I started to fall in love with my mare. When that happened, things started to shift yet again. She is now my mate, my wife. I have given her a surname, and in my heart I have taken her surname instead of giving her my last name. She is a part of my soul now... and it's painful to be away from her for any length of time. I attached pictures of my ring for her and her rhythm bead necklace, which is her "ring", to show my commitment to her.
I wanted to share this with you, as in your original post you were talking about seeing others in relationship and how it turned you on. Perhaps the reason why it turned you on is that you're now EXPERIENCING relationship with your pooch, and seeing couples together is helping you to realize that you have that with her, which sexually excited you. I am discovering the amazing depth of connection that I have with my mare, and the love that I feel for her is incredible. An animal communicator friend of mine told me that she is deeply in love with me as well, and that is a balm to my soul, to know that my love for her is reciprocated. I also wanted to share my perspective from the human relationship side of things. Relationships with humans become complex, as emotions, past baggage, and personality conflicts arise. Sexuality with humans tends to complicate things, as the women I have been with tend to use sex as a weapon to get things to be how they want them to be. I'm not trying to discourage you from trying, as several different members suggested you try a human relationship to see what you think. I agree with them. I now know that relationship with my animals is far less complex and easier to manage that a relationship with a woman. I also feel safe to love again, as I know that my mare will not break up with me and break my heart. A deeply committed relationship with your pooch will be an amazing thing. You should see where it goes!!
