Just a little advise from an old timer...
Don't cuddle any livestock. Give them a pet or a scritch and move on. It is not a good thing to have large animals coming over to "love" you. They will look at you as one of their own. And I've seen all my sheep butting each other. Ewes, or rams.
Only time my rams ever get mean is when there are ewes in estrus around them and there are other rams or even wethers close by. They aren't pushy to me but will fight with each other for long periods. I've had to work them with my border collies to get them to stop or seprate them.
I carry a training stick, it isn't big or heavy but a good wapp on the side of the face (not the forehead) will have most animals thinking twice about coming at me. I don't really like to touch my sheep to much unless medicating them or checking them over for whatever reasons. I love my sheep but save my pets for my dogs!
