I think the idea of homosexuals having a sense of their own is just a MYTH! There ARE certain words, tone, sayings they use that no STRAIGHT male would DARE use, or has. THEY are easy to pick out. Heck, it seemed to be almost innately known. I knew that even before I knew there were homosexuals.
Others seem normal, and apparently even homosexuals assume. I think I was hit on like 3 times by waiters at a restaurant. Once I figured out that most, maybe all, of the male waiters were likely homosexual, I LEFT. They were no more direct than straight women are. I never returned there. I originally went there because a church group, I was with, did.
But I am straight. I have also heard of a device called a gaydar. I saw it advertised someplace once, and several references to it. One was on a talk show, and they spoke of one for STRAIGHT people. The idea is that someone that has certain desires carries one and, when another that matches comes too close, they go off. I would get the straight one in a shot if it had a chance to become popular with women worth my time.
As for having a natural aspiedar, I HAVE noticed some. I rate it by intelligence, stims, solitude, attitude, words, senses, opinions. If they are pretty smart, have some repetitive motion, are single and not very social, are to passive or to blunt, use words past a certain level, seem to have a different level of senses, express opinions about personal space, multitasking, etc.... I figure HEY, MIGHT BE ASPIE!
