Found something nasty in my daughter's closet. Don't know how to react
Today while cleaning my daughter's (17f) room, I (43m) investigated a extremely foul smell omitting from my daughter's closet, and found something that completely mystified me, a sheltered white dad in his 40's.
In my daughter's closet, hidden behind her clothes, was an absolutely nasty mason with a die-cast of Mater the Tow-Truck from Cars (her favorite movie as a child) covered in what appeared to be two year's worth of menstrual blood and used tampons. Along with the jar were a shrine made up of the drawings and posters of Mater, some with a female truck who I assume was a stand-in for my DD, some of that were of him with realistic human genitalia drawn on him. I really don't know what to say. This isn't the kind of stuff I signed up for.
I know this stuff is common on sites like 4chan, but my DD is not the type of to use those sites. She is popular, plays soccer, and was on the top of her class last year.
I'm afraid of talking to my wife (41f) about this, as she comes from a Fundamentalist Catholic family and I don't want her to go shopping for exorcists over what I assume is just harmless teen stuff.
School gets out in less than an hour and I'm pretty sure she'll realize I've been snooping around. Please give this mortified dad a few pointers please! In my day, the most we thought about sexy cartoons were a few giggles about Jessica Rabbit, and those definitely weren't things you'd hear a popular girl talk about. Is this common among the new generation of young?
