Boy howdy, do I agree with you on this! I also think those "men" using the term promiscuity tells more about themselves than anything. I don't see that Jessica was loose. Guys will describe a girl that way for reasons other than her number of sexual partners. Rejected? Jealous? Based on the color of her boyfriends? Living at the boyfriend's mother's house doesn't make her promiscuous (as I saw on one site who also cited her age as 14 then. 14 is a child) and in fact, makes me wonder more than ever about Jessica's protection and guidance from parents. How is it okay or even legal to let your 14 year old live at a non-relative's house? Makes me angry and sad.
Depression often presents in the behavior attributed to her and it's not uncommon for depressed and even suicidal people to be described by friends and coworkers as loving, generous, sweet, upbeat, funny and happy. Anger and unhappiness would be expressed in front of parents, not unusual. Drugs, drinking and sex symptoms of depression. Sex can be used as to get the lacking male attention (absent father), affection and love when it's not about the sex act per se. I remember as a girl reading that Boys play at love when what they want is sex, and Girls play at sex when what they want is love. That has stayed with me for decades.
That culture appears to be a whole lot of territorial, jealous girls and women, and immature, irresponsible males who are either whipped or doing the whipping. I have yet to see any of them in grown up relationships. Granted, I'm seeing an extremely narrow slice of life. Fascinating, terrifying. I wouldn't want my car to break down there and be stuck. I feel like it's Twilight Zone.
Of course, this is all my opinion and I'm getting more jaded and judgmental as this goes along.
