Need for oral

When DH and I started dating he couldn't get enough of me. He practically would beg me for him to go down on me. I know that sound funny but it is 100% true. Now he always says it's his allergies. Which I understand. But whenever I ask for some play time, he would rather use a toy instead because of his allergies. Which kills me because I really miss switching it up with different things. He's such a romantic and always wants to jump straight into sex. I always want to pleasure him so I just go with it. I feel like that's worked against me now.
