maybe a point of view from one who only dances socially can help, If you love Latin just keep dancing for fun and do not focus on the technique at least at first and tell your boyfriend it just for fun and he can use whatever technique he is comfortable with , you don't have to spend time and money on coaches, you don't even have to practice moves and techniques. just put some music and dance. as you try to do so you can figure out on your own what to do.
