Hi everyone. This is my first post and I was very hesitant to make it, but I felt like I needed to. I'd really like to handle this with care and not jump to conclusions, and there's no better place that could help crack this case.
A little bit of background details to hopefully help set the stage:
My wife and I have been together for eons. Ex-professionals in the adult industry. Both of us have some very conservative and traditionalist sides to us, but overall we have always strived for a very progressive and interesting sex life. Although we've been through everything at this point, this is something I really want to handle delicately as I worry it can leave some serious tarnishing to my image that would take a while to undo.
The reason for my caution isn't just the topic alone, but rather because she has given me mixed signals. These signals are what I need your help with.
There have been comments made by her where she expressed strong disapproval of zoo. For example, there was another (quite famous) girl in the industry that is into dogs behind the scenes. When my wife found out about this, she didn't seem happy and had a thing or two to say about it. She was also a bit vocal of another girl a little while ago that gained some attention on socials because she loves dogs and had no shame in it. Other little remarks made here and there whenever it would pop up. I always aim to hold a neutral view when it comes to controversial topics, which annoys the hell out of her and also sketched her out more than a few times. But then some time passed and she brought up some woman that enjoyed dolphins (I think she was with NASA or something), but this time her tone changed significantly. She wasn't judgmental and seemed very curious how this could be. Fast-forward a little more and she began bringing up horse dildos out of the blue. I brushed it off and then mentioned it about a month later to see if the interest was still there, and she seemed extremely excited at the thought. So, I handled this part very carefully because I wanted to know whether she just wanted another large dildo, or specifically a horse one. So, I tiptoed around this and began to use the term "horse" specifically in discussion to see if the thought of that alone is something that actually excited her. I didn't go too far with questions, but I asked "Do you like that the horse cock is flared or unflared?" In essence, I wanted to gauge if it's the horse shape in particular, and found it to be the case. Now, I also wanted to know what color schemes she would like, as some people strictly stay in fantasy and will choose some wild and fun colors. They'll go as far as shunning anything that looks realistic. But I noticed different with my wife... she goes for the realistic cock each time, such as flesh colored or black or brown with some pink tones, and the designs she chose (even outside of BD's selections) were always the anatomically correct ones. I didn't tell her about EE toys, but showed her just pictures and she got very aroused by that. Now, I don't want to get too excited here, but I wonder if this is implying something...
I further tested the waters with the Bad Dragon's Sveinn - The Buck. She got very excited about that one too and asked "Is that really how they're shaped?!" And she seemed actually excited about Buck cock, and she seemed very turned on by it. Me, not actually knowing what a Buck's cock actually looked like, simply said "Yeah"

And now she wants a horse cock toy
and a buck cock toy....that's progress to me! I'm scared to pitch dog, so I'll wait a little while for that.
But of course, just because you like the shape of a horse, dog, buck, etc. cock does not mean you are a zoo. Not in my book. But it's definitely a start and it is certainly more zoo than those who outright shun these kinds of toys, which many do.
Anyways, I don't want my excitement to get my best judgement. What else do ya'll think I can do? Do you have any advice for me or anything to consider trying or asking? I really don't care if she is a zoo or not, but it would certainly be nice. Even just using animal toys is attractive to me, so it's a win either way. Part of me was thinking of buying the EE toy or something and then just casually bringing up that it's a lifecast and see how she feels about it to get a better idea. Kinda like, "Hey, you mentioned you like this one. It's a lifecast though, is that ok?" Something along those lines.
I'm about to order toys and when we play with the horse cock a few times, I was also thinking about jokingly sending her an actual horsecock pic, like a really good looking one, before playing (kinda as a teaser) and see how she responds to that. This way I can gauge how she feels but still be able to just pass it off as lighthearted...
Sorry for the long post.
Hope to hear some comments!
