Saw someone who had an experience after going to a fancy dress party so thought I'd share my similar experience.
I suspect there are probably quite a few guys who gone to a fancy dress party in drag and I often wonder if all of them got as turned on by it as I did.
In my case my wife and I swapped outfits as we are similar sizes - me on the smaller size for guy, her on the larger size for a woman so our clothes more or less fit each other. She wore my dinner suit, had her hair cut especially for the occasion and looked really hot: like something out of Cabaret - an intriguing mix of masculine and feminine.
I wore one of her floor length gowns. It was black with a long split to almost the waist and strapless. It had a lot of boning to hold it up. Underneath I wore her basque which held me in and made a very small cleavage by pushing my chest in and up. I had to shave my chest and armpits to add to the effect. I had stockings on and a pair of heels: not high by her standards but to me they were more than enough to manage. To complete the effect she made me up and I wore a long black wavy wig. From a distance I was completely convincing and even closer up it was enough to make people double take.
I found the feel of walking in the stockings and dress very arousing as the nylon of the stockings swished against the silk lining of the dress. I had a hard cock almost the instant I moved. I had not worn any panties as hers were too small but luckily the full skirt hid it completely.
During the party I saw a few guys looks at me in a way they definitely didn't when I was dress as a guy and I found I quite liked it. By about halfway through the evening I was so turned on I needed to cum very badly. I sneaked away into one of the rooms being used to dump outdoor coats and lay on the bed. I managed to get my hand under the skirt through the slit and was soon pumping away. It was only seconds before I came hard. I emptied semen into a waiting tissue and returned to the party.
The rest of the night passed with me being slightly less distracted but only a little! Luckily when we got home my wife was also as horny as hell and we made love almost as soon as we were in the door. We both roleplayed our pretend gender and the sex was awesome.
Sadly it was a never to be repeated experience, but it has given me lots of masturbatory memories ever since.
