How does anyone go about finding a legit situation like this? Servicing a straight guy? Real question
1) Whether they don't (they are bisexual in reality, even if for money, or on the bisexual concealed spectrum). Or:
2) MONEY (they stimulate themselves watching straight porn as in so many, many, many videos and the one "giving service" only comes when the cake is almost cooked to "finish" the job). Plus, many times also related to money, comes the next possible point:
3) Some people simply get stimulated with whatever object or living tissue, etc. as long as "it feels good". Whether the servicer is old, young, male, female, trans a cow or a sheep, it's not about whom or what is before them, but how it makes them feel, physically. On these people labels don't matter (what explains, also, how some of them can go chasing apparently physically inedible millionaires of any type, if the reward is good).
At least this covers most cases IMHO.
