It is my opinion, and interpretation of my own experiences, that many or most of the young men offering their services on here are primarily looking for one of three things - free housing, free money, or "being spoiled." They are universally, none of them, ready to actually perform services that would make their presence in one's home worthwhile. I have negotiated with four house boy candidates thus far who have showed up for a trial run; none were successful. I have negotiated with another five, each of whom I had a similar experience in sending them money to travel here, airline tickets, etc., and they each of them took the money and "ran" in an internet ghosting sense. All five maintain active profiles on this site.
There are some who are very appealing, but reject my interest because I don't meet their particular BDSM or role play needs.
I believe that one of the first questions that must be answered by a prospective houseboy must be what their current housing situation is. Many of these lads are homeless, or about to be. If a prospective houseboy will not clearly answer this question, one should move on to other candidates regardless of how pretty his pictures are.
