Nothing like your first assist on a calving or foaling ( not that you really assist much- Mother Nature is pretty good at this by now).
Congratulations, and even if that colt is a boy....keep IG away from him.
This all reminds me of a memory from my very much younger days. We had several new calves on the dairy farm ( I helped out an elderly childless couple with their cows and horses). I had a friend who had never been on a farm come up with me from Norfolk. He was 16 and (like all 16 year olds in the 60's) was horny all the time. The old farmer could tell that my friend was clueless about cows ( and spent a lot of time looking at the cows rear ends). He told him that if he wanted to, he could pour some fresh milk on his wang, and let a calf lick it off. He said the calf would give him a great B!*w job. After we were done milking, my young friend stayed behind while we went to the milk shed. About ten minutes later we heard him yelling. It didn't do any permanent damage,thankfully. We laughed about that day until my old friends death about 20 years ago. On a similar note, nothing humbles a young lad more than watching a bull or stallion in the mating stall.
