How to ask your boyfriend to go down on you?

My boyfriend and I have been dating for almost 7 months. Whenever we start to have sex, we do foreplay , he fingers me , we make out and I give him a bj. When we first got together I was a little hesitant about him eating me out because he has a tongue ring and I never had a guy had one before. So when he did it I made him stop, not because it was bad or nothing because I almost went through the wall. 😂🤦 But since then he hasn't done it. And miss it and want him to do it again.How do I go about asking him to do it? I don't know if I should just plan on just burst it out? I want to ask it in a hot way, if that makes sense. Help. Lol
