Yep, I've seen it. The bloke is obviously quite happy parading himself in front of a load of women. And clearly very confident, he does this for fun. That's a limited source pool right there.
Who's ‘they’?
The people who make the show.
Maybe I'm missing something. Lets set the baseline then...
They have 20 or so women who have been procurred from somewhere.... They need girls who have plenty of spare time, want to be on telly, can pop off at a moments notice or hang around for weeks on end.
.....then they have a few blokes, all of whom have met some level of criteria for being on the show. Shy blokes are no good, retiring types are no good. These chaps have to be very forward and not afraid to put their stall on show as it were. Where would they find those sorts of blokes? If you can suggest a better place than a bog standard prowl bar or club then let me know.
9 out of 10 of the guys that appear on the show are clearly just blokes who spend their time trying (and managing to), bed as many women as possible. But now they're on a TV program where we watch them do it. If you think this is not what you're watching then I understand why my post has confused you.
