Sex/blowjob

So girls my bf is saying that he isn't going to have sex with me anymore until I give him a blowy. I have never given him a blowjob but I want to for him but there is just something holding me back and I don't now what it is! He said that he will wait 1 month and if I still don't want to he will start having sex with me again. He knows that I am not comfortable with doing it and he said take your time.

I think this is kind of unfair but I see both sides of this as he has done everything to me so it's fair that I give him a little pleasure as well. But i also don't see why we still can't have sex and when I'm ready I'll give him a blowjob?

What are y'all opinions?

Is this fair?
