I have a grandfather whos in his late 70s who seems to be sexually attracted to me. I’m 18 almost 19 and its completely unacceptable for someone like that to be acting this way to me. Yesterday was Christmas and he squeezed and slapped my ass out of nowhere. Many times before that he’s been interested in knowing my sex life, asking me questions like, do you touch yourself, are you a virgin, do you have a boyfriend? Sometimes, these questions are being asked at inappropriate times, like at a family reunion or at family parties but on top of all this, he also tends to wait until I’m alone or not around the rest of my family to do these things and ask me these questions. I’m not sure what to do anymore please give me some advice. Thanks.
