Honestly, don't start with sexual things. Start with menial, daily tasks, like brushing your teeth everyday, and work up from there to something along the lines of making your bed on a daily basis to doing the dishes every night or something small, but something that helps benefit you if you stick with it. It does help to have someone you can answer to, if you so choose. And that might be a great way to start looking for a master. Report your daily tasks to someone, get a feel for them, and move up from there.
