I guess my mom is accepting that I might be sexually active even though I'm not

We were driving to a school function of mine (robotics) and I told her that this summer I want to visit my best friends in Texas because we moved and I miss them. But also because I need to visit my grandmother(she lives in Florida)and I wanted to take a roadtrip with this guy that I was dating before I moved. She looked at me and said I'm not stupid and if you're going to have sex USE PROTECTION because you don't want your future to go down the drain... And I was like 😳😅 okayyyy
