Being involved in a team of 3 is another great learning tool. I have had no issues with parents but I am in my forties and most parents are a bit more careful what they will say to one of their peers rather than somebody a lot younger. There are tools there for parents who over step the line. Senior youth is a good place to learn. I also do a bit of OA football and my advice do not stay in youth too long. After half a season try getting some adult games but also tell the appointing person how much experience you have and they will ease you into it, if they are good at what they do.
