My gelding is a bit confused!

Hey this is my first time posting on here but I could really do with some advice ! I've owned my 5 year old gelding a year now. He has lovely ground manners and although quite green in the school he's a lovely ride and a nice quiet hack . Back in July I started to notice little changes that he was doing , for example I have out with my friend and her mare a lot . He started to whinny to her ok hacks or bite her neck or bum. Out school is placed next to a field with a mixture of geldings and mares and he would call to them. It wasn't much and I could easily get his attention back . But in the last 2 months things have got a lot worse . He's started to push me around a lot on the ground , in the school he has bags of energy and is a massive fizz ball . I was on a hack and a mare he didn't know went past us and he went crazy , bucking and rearing and he tried to mount her! I was so embarrassed . This has happened when I hacked out with my friend and her mare, he kept trying to mount her and we had to go back as he got too dangerous . I had a lesson at my instructors yard and half way through my lesson one of the grooms brought a horse out the field and my horse went mad trying to get to it . In the process bucking me off . Yesterday I was bringing my horse in and my friend was in front with her gelding , and my horse mounted him! People don't want to hack out with us any more . He is literally mounting anything horse he sees . I can't hack him out on our own in case another horse comes past or we see a horse in a field and he goes nuts ! My riding instructor has told me to try global herbs rig calmer ? I really don't know what to do with him as I know what a lovely horse he is! He just seems rather sexually frustrated lol!

This is not normal behaviour for a gelding, as I am sure you are aware. He must be a rig. I would get your vet to check him asap. His mounting of a ridden horse can cause serious injury to the rider of that horse, so please be careful around other people.

Unless he has changed behaviour following a move to being out with mares having previously only been with geldings, you do not say what his turnout is, I think it unlikely that he is a true rig or you would have had this before now, the vet can blood test to find out what is going on and I would get this done asap then you can decide what to do, if he really is a rig then an operation will be required, otherwise if just down to high testosterone or behavioural issues there will be drugs or supplements that can help.
I would be extremely careful about him being around other horses if you cannot control his mounting behaviour, you may need to be extremely firm with him to prevent it happening before he causes an injury to another horse, you or someone else.

When I first got him he was kept in a field with 5 other geldings , when I would bring him in he was covered in bites and kicks and usually his rugs had been ripped. He is now in a field on his own and is a lot happier . And had been for 6 months , his attitude to other horses then started to change , and now he can't go near another horse with out wanted to mount it . It's hard as I now have to bring him in when no horses are on the yard and try to ride him in the school when the horses are not out in the field . He was such a sweet and calm horse , it's like his personality has been swopped!

He doesn't sound happier to me!

I would get a good equine vet to examine him and check his diet, making sure that he isn't getting to much energy in his feed for the amount he is using in his work. Even without the current problems, you really should not allow him to get near enough to the horses, when you are either riding or handling him to be able to mount them.
