swat didn't give us a lot to go on... but i can certainly see 2 guys with the right connection and the certain horny need making a discrete service mutually work out. It all depends on the guys, their level of trust and mutual attraction to each other, and sexual desire.
Think about it. Would the math change if one was a man and one a woman? There is still the matter of desire, of the foundation of the relationship (f*buddy, stranger, lover...) time of last orgasm, etc.
I guess I'd say good for you for getting lucky in a way you both found fulfilling.
