Blow jobs

So my husband and I of 6 months have a really active sex life, I never get turned down by him when I come at him wanting to do something, and for days he’s been asking me to suck his dick, but he mostly asks me to do it while he’s asleep for he can wake up like that, sort of as a surprise, tonight being the night I actually do it after around 5 nights of debating, he completely turns me down and says, I want to sleep. #embarrassed

What should I do?
