An older woman is hitting on me, but I’m only 16 and don’t know what to do.

Hi, so I live in an apartment building and there’s this lady on my floor. She’s older, late 30s or early 40s, and she has been flirting with me a bit. She’s incredibly gorgeous and I have considered making a move on her. But there’s a problem, I’m only 16, so I am technically underage. But this is such a rare opportunity. I’ve always wanted to sleep with an older woman. But I don’t know what to do
