First, it's been a year since I ventured out for the first time since Halloween in college, and I wouldn't have done it had it not been for this forum, so I want to thank everyone for the great advice, even though most of it was aimed at others.
I took a couple of days off from work and spent them dressed, including one evening. Last night, I went to an LGBT dance lesson dressed, for the first time. It was nothing special. On my way out, I saw a weekly ballroom dance party (not LGBT, mostly an older crowd) in another room. One of the organizers saw me hesitate and told me about the other LGBT events at that center. I decided, what the hell, I payed the admission, expecting to sit alone for the evening.
I should mention I don't pass.
Within a couple of minutes, the organizer I mentioned asked me to dance. I haven't done much ballroom since college, and not as a follower, so I was very rusty, and he taught me the basics.
Not long later, another gentleman asked me to dance. By the time I left, I danced with four men, including the organizer who I danced with several more times.
Side note: Back in college, I was fascinated at how ballroom dancing illustrates traditional gender roles. Men lead, women follow. Men make decisions, women do most of the work. I wanted to experience being the woman at ballroom dance class, which I recently got to experience!
There was no mention of my gender, and none of the men showed any interest in me outside of dancing, so I guess the low lighting made me pass. I doubt the men wanted to dance with a CD. The men were likely in their 50s, so they still have their eyesite.
