need some tips

so I recently just started being comfortable with giving my bf blow jobs but I don't really know what I'm doing. Like when I do it he trys to get me to try different things while I do it but I'm like what? like one time he wanted me to go up and down with my hand on his dick while sucking but then the skin was all in the way and I'm like what and so confused. Any thing I can try and do to make it better for him? this may seem weird but also how do I get comfortable with him looking at me while I do it? FYI I am a very awkward person with bad anxiety. Anyone who comments thank you so much I'm not going to reply as to stay anonymous.
