Fresh & Frisky Spray, Love Smitten's, and Passion Petals... ohhh my

Passion Parties.. Have you heard of these??Have you attended one of these parties??
Call me old fashion, frugal, a dud... I don't know.. call me whatever, but I have never been to one of these parties..
I feel that I am very open with my children, I can talk to them just about anything.. To a certain point, and then mom starts getting uncomfortable...
But, my 19 yr old daughter informs me that she went to one of these parties hosted my one of her girlfriends, whom is a yr older than my daughter... Now this friend is already married and has a child.. so, in my eyes that does make it a little bit different...for her, not my daughter... But, still, I do not think that my daughter should be attending one of these parties.. or for that matter have a reason to attend one of these parties...
But, now my 19 yr old daughter has informed me that she wants to host one of these parties and since she still lives at home while she is attending college... she wants to host this party at my house and wants me to attend... What the crap is she thinking??? Her reply is.. Well, mom times have changed and things are different now.. I know this and I fully understand this... But, still, is this something that a Mother and her 19 yr old daughter should share?? I am so confused..
I don't have a problem talking to my daughter about sex.. but I think that attending one of these parties with my daughter.. is a little too much for me.. a little or a lot out of my comfort zone.. Am I too far back in the 80's??
My parents never talked about sex or safe sex with me, at all... never... Finally at the age of 40.. my Mom & I had our 1st talk ever that had to do with sex..
So, I don't know.. maybe it's the way I was raised.. Some things are private...or are they????
