How do I handle my friends 16yo daughters sexual advances
I am in my 30s and a long time friend (late 40s) has got his hands full with his prescription pill abusing wife, gay son, and promiscuous teenage daughter.
I have know her since she was a baby and she always had a "little girl crush" on me. I have brought my girlfriends over and introduced them, but this has had no effect. She has always been a very touchy feely kind of person, as is her mother and father.
A few nights ago I went to my friend's house with a coworker to soak in the hot tub. His daughter found we were there and decided to join us. What followed was a utterly mortifing. She was grabbing my leg and putting her foot in my crotch and hitting on me, I expected her dad to say something but he did not. I said several times to "get off me already and keep to yourself". I switched places in the tub to sit next to my coworkers but she was not having any of it. She moved over too. I finally gave up and got out. Later when her dad was in the shower and my coworker was in the bathroom. She cornered me and in a very forward manner attempted to kiss me, I pushed her back and told her that her behavior was not appropriate and she should be nice.
I believe that she had been drinking or was on some kind of drugs. When I told her father what happened he said that she was in a "strange mood" and her hormones were going crazy. Apparently this is "normal behavior" from her. I don't think that she listens to her father anymore about the right ways to act in public. I don't believe that other men would react the same way I did and I am concerned for her safety.
How do I talk to her about her behavior without hurting her feelings and help this obviously troubled teen?
