How would you feel ?!

I know I am being over sensitive and i shouldnt take what people say personally but it's hard when it's coming from my own husband.. how would you feel? I told my husband I'm taking sexy photos for him for his birthday and his response was "I already have a ton of nudes of you, I want a necklace" 😂🥺 I was planning on taking them semi professionally by my girlfriend and I have NEVER done those kinds before so he does not have anything like they would be!!!!! I told him how his response made me sad. Like unwanted like he already has enough of me. His wife!? Really ?! Am I just being over senstive or is this normal to get upset over this situation?!
