Swallowing Question..

So me and my boyfriend were messing around the other day in his car and it got really intense and I told him that the next time I give him a Blow Job I would Swallow and he got so turned on and said he's been wanting me to... It was just in the moment I guess. But I wanted to know how it tasted. I've never swallowed before and now Im really hesitant about it. 🤔🤔Thoughts??
