Lots of really good advice here so far. You definitely have to take things very slowly and let things naturally go from there. Watching IR porn together is a great way to start. You will learn a lot just by her reaction to it. Point out things like how amazing the skin color contrast is. After watching, I would wait a couple weeks and see if she brings it up. Best time to bring things up is during foreplay, and when she is super horny… tipsy helps too!
