new to kinky and bdsm

So I've met a guy who is heavily into kink and fet lifestyle. I've never really done anything in this world but i want to learn. He's a natural dom/top and plays hard from what I can gather. He draws the line at knife play. Currently there is nothing physical going on but he's told me he wants me and his flirt game is unraveling me. I'm a naturally in control person and not sure i could be a sub/bottom. Would he get bored if i can't keep up or if I'm not comfortable with others watching or if I'm not good enough? would really love some advice from women who are deep into this world...
