To me as a parent, sounds like your parents are supportive and also want to give you your own space so aren't about to bring it up again the next morning. So kind of awkward but at the root not a huge deal for them?

I'm sure if you aren't up to it they will take the lead at some point and bring it back up. But if you are up to it and want to broach the subject you have the opportunity to kind of set the frame for the conversation where you want it. I.e. less on trying to pin you down on your sexuality and safe sex practices. And maybe more on how they can support you as you continue to figure out and live your life.
