Just little things with my guy. When we go on walks, he knows that if we go to the Left, it will be a short walk and if we Right it'll take us long route to the Dog Park that he loves to run around and explore in. Other things are, him nipping at my arms if I try to eat without him. I don't eat without him too often, but if he notices me eating while I am cooking he gets bossy and will nip at my arms to keep me from "Sneaking" food.
But when it comes to anything sexual, he won't fully try to mount me, but he will scratch or nip at my back pocket. A subtle way of saying "Hey, bend over." If I am already sitting he'll bite my sleeves or the bottom of my shirt/hoodie and pull me to the bedroom or the back door. But this doesn't happen all that often, I usually get surprised when he makes any romantic demands. I think that my K9 wives in the past were far more expressive when it came to sex and romance.
My wife Lex was very touchy feely, she often climbed onto my lap in front of people and would put her face into my neck for cuddles. She would back into my crotch if I were sitting, to let me know that she was ready for me. Sometimes I am baffled as to how my friends and family never realized that I was in a relationship with my past wives, I have always been openly affectionate with them and my wives continuously showed me when they were ready to breed, when they were in heat.
