Is it normal for a friend to be so loyal?

ok i have a bit of a problem, i cant stop thinking about having sex with guys, but im completely straight

the way i got over it was through my friend steve, he told me he had exactly the same thoughts, constantly thinking about having dicks in his ass, but he was straight too!

anyway, what solved everything for me, steve would invite me over to his house every week, and let me give his girlfriend anal, i never got to see her as i was blindfolded the whole time, as i think she was shy of being seen, but i totally stopped thinking about cocks! i meet steve every week, i still cant believe he lets me do this to his girlfriend, he says i can do it forever so long as i never take my blindfold off and keep my hands behind my back not touching her

pretty good deal if you ask me!

so what im asking is, is it normal for a friend to be so accomodating and caring, i have never met one as nice as him before!
