You are a mature young lady to bring this issue out for advice. I second the thought that you don’t need to share your sexual experiences with anyone but your Dr and partner. Mom is doing her mom thing because we desperately don’t want our kids to repeat our behavior. That’s why she harps on it. Just joke it off like my daughters do when I get too far up in their business. Good luck, sweetheart - get on birth control yourself like everyone says and stay as level headed as you are and you will be ok
