I'm a fairly slight male, with a somewhat smartass or ironical nature, take your pick, so in my younger days I was hit on not infrequently by some men.
I was always flattered, but never ecstatic, while when on estrogen, and fully dressed as a woman I received the odd compliment, from a man or woman, or a social nicety, my heat would flutter and I would be filled with joy from the top of my head to the tips of my toes. The only sexual reaction would be, I swear it's true, my nipples would get hard.
This caused me to come to the conclusion that this affirmation resonated in some fashion deep into the core of who I am.
And it was great fun.
