So, I know I am late to the party, but...
I grew up in purity culture
@Tetra and I experienced negative impacts as well.
To give you an idea:
A crush was considered an emotional STD, it would poison and potentially destroy any future relationship you had. Every crush you had was a piece of your heart that you could not give to your future spouse. You were to marry your first crush.
Arranged marriages were a thing because of this.
Any feelings, happiness, anger, sadness, and sexual attraction in particular, was evil via proof-texted Jeremiah 17:9.
Hand-holding, kissing, and hugging made you damaged goods, spit-in water, de-petaled flowers, etc.
Virginity = purity, purity = virginity. So when you got married and "lost" your virginity, you also "lost" your purity.
Virginity/purity was lost through use of tampons, pelvic exams, and sexual assault.
Most of us were not allowed to go to the doctor, because they were evil, but pelvic exams were a huge fear for us girls because of this when we were older.
One of my friends growing up was raped by her older brother. He put a sharp object to her throat, took her to the parent's bedroom, and raped her.
The parents blamed her. I heard, "He had his five minutes of fun" so much it made my head spin. The community blamed her. They called her every name in the book and said she deserved it and no one would want her now. She was impure, tainted, disgusting. The girl's family went to jail, all the while they and the community contended that nothing wrong had taken place.
Anything that happened to you as a woman was your fault, because of how you acted or what you wore or what you said.
We were expected to swim in jeans and long sleeves so we wouldn't tempt the boys. We were not allowed to wear sandals because one of the father's had a foot fetish. The other mother's would watch us pass in the hall and scrutinize our clothing, randomly pulling us aside and publicly shaming us for not knowing how to adjust our bra straps in early puberty. They fell down and, as a result, we were tempting their sons and husbands.
I could tell so many other stories, but I'll stop for now.
The bottom line was that purity was your whole identity. This was the most damaging thing for me. My worth and identity was in what I had and hadn't done sexually rather than in what Christ has done for me.
I waited, just like you
@Tetra , and I watched as all of my friends walked away from the faith because they were taught that God cared more about their ability to follow the community laws than them.
I don't know if you are familiar with the Gregoire family, but both Sheila and Katie talk about purity culture. This video of Katie's is fantastic:
I have all sorts of folks identify with what I say, many of them atheists and agnostics, but our worldviews are drastically incompatible. At the end of the day, I know who I am in Christ, they don't, and that changes everything. That is why I added that this explanation of patriarchy makes sense, socially speaking. I appreciate you mentioning this and looking out for me, a lot.
