Handjob help/ am I being selfish?

Hello ladies! I need some helpful tips on giving a good handjob. I am new to this stuff ( I am 21y/o) and I don't know what I am doing. This is the first guy that I have dated and wanted to do things with. He knows that I am a virgin and is super patient with me. Any tips for a good handjob? I have touched him one or twice. He was all sticky and I was not sure if I should spit on my hand? What to do with my hands? I did not cum the few times I have touched his penis. I feel slightly bad that he gets me off (from dry humping with clothes on) and he gets nothing in return. I expressed that I felt bad, and he said it was totally fine, not to worry. Why do you ladies think he is so ok with that? He said he just wants to make sure I am happy and comfortable. Usually guys don't respond this way. Thoughts????
