How to talk to your parents about dating, when you don’t talk about your love life with them?

I am currently talking to this guy that I met in school and we get along really well. Text a bunch and sometimes FaceTime (since we cannot see each other in person at the moment). But he recently confessed his feelings towards me and I told him they were mutual, but want to takes things slow.

I am scared to talk to my parents about this. I want to be able to go out with him (when we can meet up in person of course) but just thinking about it makes me really anxious. We never talk about this kind of subjects and so as a result they never said either way if they will allow me to date or not. Technically I am an adult, but would still like their permission and feel like they should be knowledgable about this aspect of my life. I would feel guilty about trying to hide this.

How would you go about bringing it up and what would you say?
