Oral - Tips please!!!

So the guy I’m seeing insists that he has never came from oral. He’ll be 40 this year.

When I’m giving him oral, he enjoys it, moans, cusses, back loses rigidity, legs all over the place, etc. I make sure when I’m giving him head, its wet, deep throating, hands, no hands, massages and sucking on his balls, eye contact, breasts, etc. Nothing will get him to cum from oral.

He says he’s fine since it’s something that has never happened and just enjoys it. I’m frustrated because I want that for him and... tbh... This is new to me cuz I’ve been able to get the men I’ve been with before him to cum from head alone, and I really want that for us.

If you have any tips or things I could try, please let me know!
