He doesn’t finger me

So me and my bf have been together for 6 months, he refuses to finger me or go down on me. But he still expects me to go down on him, i used to but lately i told him if he doesn’t want to please me then i won’t please him, is this wrong? His excuse is “ it takes me a while to want to” i think that’s bull shit, the vagina needs to be touched and rubbed right? He gets mad that i refuse to give him head now, but it’s only fair
