I think that they're bachelorette parties. Usually the male strippers are both black and white, often more white, with one or two token blacks. The alcohol is the catalyst. They started in England and came over here. I think that the blow jobs are real, with lit-up participants joining in after drinking and being encouraged by their peers. I'm not sure about intercourse shots. They may, in fact, be prearranged, since the party shots are sold as porn. There used to be a protocol where a stripper would use a towel and whipped cream to provide some privacy and an incentive to amature participants, but they seem to have moved away from that. The first time I saw this thread, I found several firms that schedule these parties for bachelorettes and others by google.
