Jennifer, firstly thanks for sharing this episode. In some form, it's happened for many of us.
I think the validation aspect (as previously mentioned above, including by yourself) is...well...valid Your guy is apparently something of a charmer, and for him to be attracted so much to you must have been thrilling. No surprise here that you responded as you did. It's what pretty girls do.
Regarding sexuality (and this is strictly about my own; obviously each of us is very different): for me, the dressing came wayyyyy before the gradual movement from heterosexuality to bisexuality. Without a doubt, being seen as an attractive female sort of opened me up (no pun intended) to crossing what I had perceived as boundaries. Now, it's less about the "plumbing" than it is about the person-to-person attraction.
Again, thanks for sharing. The responses have been as interesting as the original posts.
