So my bf, who I've been dating for a year and a half, and I were making out last night and I was giving him a hand job. I've never been confident in my ability to give a blow job but we're very open about the things we want and I know that's what he wants. It's not that I don't want to, I just don't have the confidence. He finally realized that the idea was really stressing me out and he just scooped me up in his arms and kissed me on the forehead several times saying "don't even worry about it" but I want to do it for him. Any tips on how to gain that confidence?
