handjob help!!

Ladies! I need help, my bf and I are taking things slow and we started doing some hand things. And tonight when we were making out I was so close to giving him my first handjob, but I couldn't because my family was in the other room. He was being nice about it and said that we to practice more. I know lube helps a lot, and he's not shy about telling me what I need to work on. But what is some advice all of you can give me??
