I seen it both ways working in high school. I know high school girl seniors who target freshman, sophmore. One girl told me the younger dude have more stamina during sex. Senior guys target the freshman girls the first week of school. We do our best to keep them out of the freshmen halls but you know they get to them anyway. And then they do expose videos (which are illegal but these idiots don't care) of these freshmen sucking them off.
As far as older men, younger girls. It's basically these dudes playing the father role in their lives. THey love that he got money, a car and they gladly give him sex. But in a lot cases, these dudes will ask or in some cases blackmail these chicks, into banging their mans. And if they don't then they dump them. These girls actually think they're in control, when it's actually this old dude (30-40's) in control.
We had a situation some years ago when one of our high school girls was getting used by one of these older dudes. Had her in rap videos shaking it and everything. Well, my boss confronted the dude and for legal purposes I won't say what he did. Let's just say he got the message that if he didn't leave her alone.... She got rescued, got her life together and is now an attorney in ATL.
Bottom line, these young girls need men to play the father roles in their lives. Having uncle or positvie role models who will give them the attention they need but ain't trying to hit. Though my goal is to reach young Black males, I have plenty of young girls who hang around me at my school because they just male attention. And with some of them, they'll actually listen. Of course, a lot won't and just lost. And when you give them that attention without being a pervert you have their ear. Can't save everybody of course.
