Feeling very Undesirable 😔

Ladies... my husband and I have been having a lot of problems lately... and recently in an argument my husband told me that he doesn’t want to go “down” on me because “it’s gross”... now, mind you, we’ve been together for six years so obviously we’ve had lots of sex and done lots of “things” and he’s literally NEVER once said that it grosses him out. Am I stupid for this really hurting my feelings? 😭 I felt so sad about it that I just said it was fine that he didn’t have to do it anymore and that I was just done.. I just don’t know what to do 😔 it makes me feel very unwanted
