New sub ! Advice

So I recently met this guy and pretty quickly he let me know he was the dom making me the sub which is perfect because I’m already really submissive naturally. Prior to this most my sex has been pretty vanilla. I never knew anything much about bdsm so I’ve been trying to educate myself and be prepared. I’m having fun and enjoying my self... we are trying things but at a slow pace so I don’t feel overwhelmed. It’s exciting.. I love when he tells me he owns me:) He hasn’t mentioned using a safe word and that’s okay bc where we are at now I don’t think it’s needed but maybe soon? We’ve been seeing each other for about two months now. Any advice for me in general just getting into this and being a sub for the first time? I want to impress and please him
