So, I got my APHA Gelding in mid april of last year. The mare I have had for 14 years, she never gets along with any other horses, except for our old shetland, but he since passed. Well anyway, I noticed about a month or two ago, when they were playing the in the pasture that she was in heat (which isnt rare for her. lol) and 'squrting' at my paint. And he was going along with it, jumping around ect. I went back to doing what i was doing, looked back up when I heard my mare squeel, and he was mounting her. Not just in the process, but his front legs over her shoulders ect. Since he is gelded, he was not...uhm...'hard'.... but was acting like he was. I know he was still a stalliong at 8 months, and I know he was a gelding at 7 years, but inbetween then i have no idea when he was gelded. He is now 10. I really have nothing to worry about, except for him hurting her, which I doubt, she is tough. lol. I('m glad to see she actually likes someone else, maybe a little too much. But has anyone had this happen before?
