Massages

Does anyone have any tips on giving a good massage? SO called me during lunch and told me his boss is being a pain on his behind and has them working alot today and asked me for a massage when he's home. I've given him massages before we even tried oils but felt to gross for both of us and didn't like it. I just want to make him feel super relaxed, I usually sit on his back, almost on his butt and massage him that way but I want some better massaging techniques. TIA☺
