A houseboy position involves performing some household duties while also being an attractive distraction to one's employer. It's a position that is often compensated with room and board, and often some type of additional stipend. Some physical intimacy is generally included into the bargain. This may range anywhere from a "uniform" whilst on duty to free-use agreements and even TPE or Total Power Exchange and any number of other negotiated fetishes and/or kinks.
Personally, as an older gay man, I tend to come down on the least demanding end of that spectrum. You can find a fuller description of exactly what I'm looking for on reddit if you check the /r/houseboypersonals/ subreddit and search on Ganymede.
