Ways to overcome fear of swallowing his cum

OK. Sooooo the description says it all. I have swalled once. Well, I tried. But I was laying in a bed a I just remember that it shot so fast my mouth literally filled in one second. I swallowed but by time I tried to swallow again there was just too much and I choked and I got all over the place... Long story short it was a bad experience and it tasted horrible. I know that my fiancé will want me to do it again. How do you guys do it? How do you get over the taste and the texture? Suggestions?
