I haven’t tried Mystery Boy, but I know exactly who’s posts can help you out. Look up R0N’s posts. I don’t know if he’s active still, but IIRC, he was a gay escort in Canada. I’m sure his posts will reveal all the pertinent information. Anyways, I think that is a good place for you to start, as mystery boy isn’t the end all of homosexual attraction.
Good luck, and even though most of us are breeders, we’ll help where we can. 
As far as recommendations go, I think Instant Honesty might be what you’re looking for. You can get ToGos of it to try. If you’re trying to attract people, Instant Shine might work for you, all people tend to like people who make them happy. It might be expensive at this point since you’re a newer member, but p93 reportedly has good male bonding effects. But take a look at R0N’s experiences and go from there. I’m sure he can shed light on matter much better than I can since he has used them first hand in an effort to make guys more comfortable around him.
If you haven’t read this thread yet, I suggest it. Gives a lot of information on how approach the situation.
