Maybe TMI but need insight/ advice

My hubby is a big guy and I give him BJ's with little argue. I am a curvy girl myself but I can't seem to get the favor returned. He did it once and made comments like yum, or whatever so I'm assuming it's not my Karen. He claims he had a semi-scary experience going down on a chick so now he claims he has a phobia...

Idk. .I would just love to feel his embrace. Do I sound selfish?

Our sex life consists of me on top or me giving a BJ 95% of the time with the off chance he may try something else 3% of the time... 2% is self exploration
