Initiating oral

Hello! I have been seeing this guy for a bit, and we recently just started to have sex, and it's been amazing. I love to give head but I've noticed he hasn't tried to return it in that way (makes it up in other ways lol).. And I definitely want him to, how should I bring it up? Or is there something I could do to help, if he's just nervous? Thanks for the help I appreciate it!😊😊
