Yesterday when I went to see my mare she was without a doubt in full heat. I could tell as soon as I took her out of her stall as she cut in front of me to block me from walking(IMMEDIATELY REPRIMANDED...I don't care what's going on with her, she is NOT allowed to disrespect me). Took her into the arena and decided to just let her roam around for a bit while I looked for something in the tack box. There are two stalls in the back of the arena and this is where she went immediately. After about 3 minutes, she is squealing and urinating and showing herself to a 4 year old MARE that was in her stall (there is a gelding over there as well but she was flirting with the mare). Is this typical behavior? When I walked into the arena she pranced over to me and respectfully asked to come in so I let her walk up to me. After petting her neck for a second she turned her rear end towards me and presented herself to ME, urination and all. I just ignored her as I have heard that it is a sign of respect because she sees me as high enough to "breed her." Now of course I know that my horse is not a lesbian LOL I am just wondering if it is typical for a mare to show to other mares or human females.
Thanks for reading
