Consider if Big Al is humping limp-wristed faggots (and I do NOT know if that is the case) for extra money in the porn film game, why would he want his hard-working wife who puts the bread on the table to know about it.
Of course, all of this paid-for-pumping could just be some jolly repartee by a bored railroad worker with time on his hands. But if somebody has delusions of grandeur stemming from the investment in NVEI bearing fruit, who is say that he does not have flights of fantasy about being a stud actor in porn films.
Once you are deranged, you can go in many directions they say.
