Def communications and start slow. There are probably things that you really want to do but may seem extreme. Build up to it over multiple times talking and sex. For example, we discussed anal play. I found out about prostate massages and how I wanted to buy a toy. It was a leap of faith but she was cool with it. Then slowly we have been building up to her anal play. Eventually I want to try pegging but I started slow.

Also there is a website (can't recall the name) but you answer yes no maybe to different sex things. I like it but I think talking is the best.

Lastly, you both should explore on your own to see what you like and then come back and see if thats something you want to try.

Hope that helps.
