First Kiss Dilemma plz help

I (15m) have been dating a girl (15f) for about two months but we have known eachother for about 8 months. We both really like eachother and everything in our relationship has gone really well except minor awkward moments here and there. My parents are somewhat strict no social media like Instagram or Snapchat etc and they are a bit overprotective in my opinion. We started talking and earlier this year she gave me a peck on the cheek for my birthday and it was nice but I haven’t told my parents due to the reason above. Anyways she’s very close with her parents and talks to them about everything which I think is a good thing but recently we got into a conversation about an actual first kiss and we both want to but I really don’t want my parents to find out and she is going to tell hers eventually not immediately. I have no clue what to do and I am worried how this will affect my relationship with her or my family in the future. Please help me I am stuck and I don’t know what to
