The only time I gave head

My SO and I have been together a long time. Towards the beginning of our relationship I got really sick and sometimes I get a little sick-horny. I made him cum and my first reaction was to try and Swallow. Mind you I have the world worst gag reflex I puke at the sounds of gags, certain textures of toothpastes and whatever else. I ran to the bathroom  puked a couple times and he came in after me sat down pulled me into his lap and ran his fingers through my hair while tearing up, and said "we are never doing that again" he felt soooo bad, because he felt as though he took advantage of me. I love that I have someone who cares so much about me.
