Should I just tell him I want to??

I want to give my boyfriend oral but I honestly don't know how to go about it. I've had sex with a past partner before but literally have never felt the need to give head. So now with my current boyfriend, we've been bestfriends for a long time and we're super close but we just started exploring being sexual with each other since we're together now. I literally want to so bad lol I know I shouldn't be but I think I'm just afraid of what he might think of me. Should I just go for it?? or like tell it to his face??? idk "hey i wanna give u a blowjob" sounds pretty awkward dude idk!! again I know I'm probably just over thinking but reassurance and advice would be nice man peace out
