For me, sometimes and most of the times riding a stallion can be just as fun and relaxing as any other horse. I have gone bitless and bridless and felt safer on the boys honestly then my mares. But it depends on the situation and the other horses around. If there are other stallions or mares in heat it can still be fun but I end up being super alert to any changes or signs that my horse may decide to do what he wants. Mares in heat are not so much my worry mine are pretty well behaved and can work next to them without a problem. Working with or around other stallions..not so relaxing. Having another stallion riding near you that wants to tear the one you are on apart is not a pleasant feeling.
