At what age is too old for a daughter to kiss her dad on the lips?

[inneedofhelp91]

I have been dating this guy for almost 2 years now. His daughter is almost 17 years old. She cuddles with him on the couch, kissing on his shoulder, kissing on his arms, rubbing on his stomach. She was lying on the couch with him, she had her head on his lap and he was rubbing her back. She laid there for hours that day. She kisses him on the lips before she goes to bed at night. She runs around the house in her bra and underwear all time. She is even now starting to run upstairs naked while her dad sits on the couch and can clearly see her running upstairs. She says "Daddy" dont look im naked. And yes she still calls him "Daddy", and talks like a baby around him. It drives me crazy when she does this. I have tried talking to my bf about this and he just says she is "Daddy's" little girl and always will be. I feel I always will be second best to her. I mean I have been putting up with it for 2 years now. I raised one daughter of my own and I have never ever saw anything like this. My bf says it is normal for a daughter to kiss and rub all over her "daddy", I told him no its not normal for a daughter at her age to do this. She even came into his bedroom not too long ago and crawled in bed with us. Laying her head on her daddy's shoulder, then she started kissing it. I got up and left the bedroom. I refuse to sit there while this is going on. I cant take it. It freaks me out.

I truly believe she is crying out for attention 2. The kissing on the lips n the calling "daddy" is bad. The cuddling and the running around in the bra n underwear is what is bothering me more than anything. Again I truly appreciate all the opinions that everyone has giving me. Thanks again.

The running around in bras and panties and the amount of cuddling seems suspect to me.  As far as kissing on the lips.... my sister kissed our dad on the lips until he died 15 year ago.  She also called him daddy.  (In fact, I know a lot of women who call their fathers daddy... the kiss on the lips and the "daddy" calling aren't the problem.  Personally, I'd have a problem if a 17 year old girl was calling her daddy, "Frank, Robert, Thomas, or whatever his name was.)

Good points on dealing with the situation from everyone.  Can I just throw one more thought into the mix?
Sometimes inappropriately sexual toned behavior (which I think the running around nude and the caressing etc is) can be the result of being or having been sexually abused in the past.  I'm not saying the father has abused the child but could something have happened/be happening with someone else in the child's life?
This seems like it could be a cry for attention, especially since the behavior is escalating.

I was just trying to get people opinions here. That is all. Sorry you all feel that I want to vent here. I didnt mean to come across like that. Once again im sorry if everyone thinks i was venting.

I'm done too, SpecialMom.  This seemed like a no-brainer to me from the get-go.
