UHHH

I know this girl from before she was born, my parents knew her mom since before she was born, and we spend every summer together. This summer weve been talking more. Shes almost 17 and im 19, and shes asked me about the legal age people have to be to have sex with eachother, the other day i told her i went to a bar and she asked, "did you use a condom?" and shes been telling me about her boyfriend who got in trouble about something and her dad wants her to break up with but she would do anything for him. Weve talked about sex positions, 69, which she replied to with, "you got it." What do you think about all this?
