First time please help

I have been with my boyfriend for about 9 months now, and he has always been willing to eat me out or spend so much time pleasuring me, and I haven’t been able to bring myself to do the same for him. He is slightly more experienced, so he’s more comfortable. I don’t want to give my first blow job or hand job and have it be an absolute horrible experience! Any helpful and/or comforting advice appreciated😊
