Sex toy drama

I’ve only ever been with my husband since I was 16 had one penis my whole life I’m now 36 and he wanted to introduce toys I was up for it no problem, he’s a good 5 inches I’ve never had complaints :) the new toy is like 7in and now because I liked it he keeps telling me I like big dicks and says he can’t have sex with me the same knowing I prefer bigger which is not the case I still would just prefer him over any toy. But now he’s playing victim in a problem he created. I don’t know how else to explain it to him.
