There were support groups out there, just not a lot of them. You'd have to go to a major city, and, there was usually just one even there. The only reason I knew about other men who crossdressed was from the Kinsey report. That was all I found for years. No one else was discussing us, as it was just assumed by all that we were gay or transsexual. There were also clubs that catered to fetishists and alternative lifestyles, dom/sub couples, etc., where we could go and be generally accepted (although there were always a few who thought their own kink was perfectly normal, but everyone else was weird). But again, you wouldn't usually find these clubs outside the larger cities. A single male going to those clubs had about a zero chance of finding a single woman there, at least that was my experience.
