Doesn’t ask for a BJ?!

So i don’t know but this seems a little weird for me.

So my boyfriend always wants to pleasure me by fingering me and going down on me but every time I want to pleasure him he just grabs my hand to do the job but he NEVER mentions me giving him a blow job. I find it kind of weird that he doesn’t want me to do that or doesn’t ask me since he goes down on me all the time.
