I am not very confident with giving BJs, I am not sure why. I have a new partner and want to please him; he has cum from a BJ I have given him before but, I dunno, I feel like I could be more confident and certain in what I am doing rather than just bobbing up and down. And what am I supposed to do with the foreskin? Do I have to deepthroat? I am probably overthinking this but does anyone have any tips?
