Wax Play and Anal?

So my partner and I have decided to try a few new things in bed because right now we’ve only played around with like the basics of bdsm and very light things. He’s interested in wax play, has tried it on someone before and I am very new to the idea and have never experienced it. He’s also been really wanting to do anal and put a butt plug in me which I am down for though a little skeptical. Can anyone give any pointers or what to expect with either/both?
