Is not giving her an O yet a dealbreaker?

I’ve hooked up with this girl only 5 times over the past couple months because we travel so often and I have FAILED to give her an O yet. I am a bit of a baby gay, but I feel I suck at going down on her.

Would you end things with a girl you really liked if she couldn’t get you off after a few times in bed together? If the attraction is still strong?
