You probably will be a better lover.
Ask the SP's on what you want to do (cunnilingus, how to ask for permission for things and not be an asshole, spanking, choking, DATO, etc.. just try stuff out) and kind of see where you are yourself and be comfortable.
I usually find that the ladies that work in this field are the LEAST judgemental and sometimes super sweet individuals - I guess they must have a great deal of empathy in order to overcome the stigma and truly provide a good service.. I'd recommend some older (like early 30's, late 20's) SP's and "learn" as much as you can..
If you just jump in with a 19-20 years old they might be as lost as you are.. LOL...
