big shocker here, but i wear i lot of tie-dye shirts!!
most of my chams, whether m or f immediately assume a threatened pose if i come up to them with one on. and they are always looking at the shirt, rarely at my face. so i’m careful not to wear one if i have a bunch of work to do with them.
another time i was going to pick up one of my large males and he was bugging out, staring at my head, gaping and puffing. i realized i was wearing a tie-dye bandana…..took it off and he was much happier to see his daddy.
finally, about 15 years ago i had a nosy be male that i studded out to a client’s female. that was his first and only experience with a lady cham. but ever after that, my at-the-time girlfriend’s muddy brown/pink sweatshirt became his humping post. he had never reacted to it prior to the mating, but after if she was wearing it he would start the head-bobs, coloring up, and would walk back and forth on her arm looking for a hole (literally! he once found a small tear and when his junk began to come out it was time for him to get off of the shirt!)…….it was hilarious, educational, but somewhat bittersweet. so in this instance at least, it took him an initial day of whoopee before something clicked in his brain re: those colors.
o-
i dont plan on breeding my guy so i dont think ill have to worry about him thinking the same thing your guy did 
Oh well. I won't let little Mo see it again.
