I am so confused (TMI‼️‼️)

Don't make fun of me please ( need help) but I been in a long term relationship for about 2 years and 6 months right and we have sex a lot like a lot. He likes when I swAllowing his cum always have but I am not the biggest fan because it makes me sick to the point where I feel like I have to vomit. Like for example, today we had sex and I swallowed his cum right and then (first time) throw up is there something wrong with me ...
