Hi, marinegordon, and welcome aboard CF.
You're fortunate that you live where there are lots of sailors. Why not toddle down to the local yacht clubs after races, and sink a cool one in the bar and meet some of the guys? That way, you can start your learning
process on other people's boats, which is how I started sailing. Depending on your experiences, you may want to take lessons at some point, but it's not a requirement for having fun on sailboats.
About getting turned on by u-tubes, just remember they don't totally reflect reality, and you'll be okay. Just use critical thinking in applying them to real life.
