From what I know of Purity Balls, they don't go into the whole "Father owns daughter's virginity" thing. It is supposed to be a ceremony that makes a girl feel special and then she will promise her dad and her church that she will not have sex before marriage. Girl gets a little ring from Dad and they dance and blah blah blah.
I think it is incredibly creepy and honestly, I think my father would have RUN if anyone had suggested it when I was a kid. I know my mom would not have allowed it if was a thing then because it is just creepy. Also, she had a real strong feeling that your body was YOUR body and permission to touch it came from YOU, not mommy, not daddy, not anyone else. It didn't make her popular at the family reunions if we refused to hug some relative, but she sided with us every time. At no point did the topic of virginity actually come up in discussions about sex,love, marriage or whatever other than to explain what it was and that most girls actually lose it due to some type of sport - horseback riding, soccer, baseball, whatever. So that whole barrier thing is more of a myth for most of us because we don't really realize when we lose it. Unless you are like a very unfortunate college friend of mine.
I went to the gynecologist with her after a few questions made me think something wasn't right inside her. She was scared to go alone. She was one of the few with a very thick hymen and needed a procedure to fix it. I knew the doctor at the clinic I took her to she explained a LOT. That was where I learned that the whole hymen breaking during sex is far from proof of virginity and that for a rare few girls it is proof, but for most of us it is long gone due to school gym classes and sports.
Honestly it was the last I thought about the subject until the Purity Balls came to light. I think that the emphasis on a girl being a virgin is dumb and unprovable. Plus I knew a TON of girls who were 'virgins' on Sunday through Wed or Thurs, but come Thurs or Fri to Sat, they were with whomever wanted them. I never understood that, and still don't, but they would swear to it.
EVERY girl I knew who did the whole "revirgin" thing, had parents who took them to some fairly strict church. Those few who had parents who left our religious choices to us never seemed to feel a need for that, or to discuss our virginity with the world at large. We never seemed to feel our worth depended on it. I think it is a fault of many of these churches. If I look at the parents in these churches, I can identify very large percentages who are not faithful spouses and who seem to want their kids to not know this. But kids always know, and "do as I say, not as I do" hasn't worked at any time in human civilization that I have seen. I also never heard any parents go on about the boys remaining pure until marriage. They are still supposed to be wild until marriage, which is more than a double standard to me. I don't judge these churches site unseen. The observations I have made are based on having attended church with friends of many religious types as I explored to see if there was a religion that suited me. One thing that really really really bothered me was that in several of the churches in town the boys were given totally different messages than the girls. There were several groups of men in town who would organize a prostitute to 'teach' the boys about sex when they hit 14 or so. In my opinion, that is as wrong as a Purity Ball. It was to make the boys 'men' and 'good husbands' because they could then teach their wives about sex when they married the pure, virginal girl. YUCK!
