Should I talk to my bf about getting head elsewhere?

Hi all so this has constantly been an issue for me (23f) and my bf (35m). Everytime I bring up him giving me head he says he’s not into it and doesn’t like doing it yadda yadda every other male excuse and basically it’s literally the one thing I want. I’ve never experienced and by god I really want to it’s driving me fucking insane. So I’m wondering if I bring up with him the idea of getting oral sex from someone else? Not that I know anyone presently but being able to have the opportunity to get it elsewhere and only oral nothing else. He hates the idea of sharing and what not so I would hate to bring it up and have it crush him so are their any ideas on how to bring this kind of thing up? Tia x
