My boyfriend is mad at me for using a toy

Im pregnant and right now its hard for us to find a position we are comfortable in. He knows I have a dildo and said he would use it on me. When I pulled it out he said “Really? This thing is bigger than mine” He immediately got turned off and said that it felt disrespectful and came off as I wanted something “bigger and better” Hes more upset than anything and now I feel like shit.
