NSFW massage tips

Hey, I'm a (23) gay guy in a relationship with my (22) boyfriend. He's very much into hands and massages and while I'm not completely new to giving, etc. I was wondering if there are any tips and tricks to the trade? I've scoured videos on The internet as to different techniques. Hands/touch are comforting and erotic to him.We just bought massage oil the other day, etc. and I'm excited to try it out (as is he). We've chatted about his interests but I'd like to be able to surprise him a bit :)
