In my experience it's pretty hard stopping people from calling you nicknames, if they feel like doing so. I've never introduced myself with a nickname to anybody, but somehow they often end up using one anyway. Then, a name is really something other people use for refering to you. Whatever is more convenient for them is probably the best name.
