My counsel is don't be in a hurry to find a Master. You're young, there is no urgency. Instead find out more about your local community.
You can meet doms on sites like this one, fetlife, collarme, informedconsent and a dozen others, but if you're inexperienced you've no idea if they're spinning you a yarn, if they're really as experienced (or inexperienced) as they claim they are. Nor how safe.
Look up your local munch, fetish club or similar. Meet with other submissives and work through with them what you're really after, how deep you want to go, and more importantly who on the scene is considered safe or not. From there you can progress your kink safely.
Unless you just mean you want a boyfriend who spanks you and ties you up for sex- in which case disregard any of that last paragraph.
