To answer the questions in order, I have never met or heard of a guy who has a desire to wear high heels outside of the online community. It is unlikely that it's the case, but as far as my own personal experience goes, I'm the only one.
The answer to the second question is no, the thrill hasn't faded much at all. To be sure, wearing heels is ordinary to me, but I will say that when I put on whatever shoes I'm going to be wearing that day and stand up, feeling the full height of the shoes for the first time since waking up still gives me the same feeling it always did. That has not faded over the years. What is different is that sometime over the last 12 years, I now require more steepness to get that feeling. 12 years ago, in 2012, I started off in effective 3 inch heels, and I very clearly remember my first real walk in them. It felt like a mile was going to last forever. I could not WAIT to get back home and get out of those shoes. My very next pair of shoes, bought several months later, had a 4 1/2 inch heel with a 1 1/4 inch platform, so effectively 3 1/4 inch heels. By this time, I was somewhat better at heels, but 3 1/4 inches still seemed pretty high to me, definitely felt like a heel.
I started actually walking places in heels in 2013. I had a few more pairs by that time, but most of my walking heels were in the 3 - 3 1/2 inch range. Over the years, this has gradually increased to the 4 - 4 1/2 inch range. 3 inch heels no longer do it for me, and I have proven this in the past week, as I have been wearing lower heels (the few that I have left) in an effort to avoid further injury. I'm trying to take it real easy, hoping my Achilles tendon gets back to normal soon. The last three days it's been feeling pretty good, but I forced myself to wear low three inchers this morning, even though it feels like I can do more. It's just not the same. On pavement, it doesn't even really feel like I'm wearing heels. I was a little bit grumpy wearing the shorter heels. I need around four inches of steepness before I'm thinking to myself, "Yeah, this is the life."
As to the third question, I'm with Shyheels on that one. If I'm putting on Hunter boots, it's for work purposes. I've never thought they looked all that great as a fashion statement, no matter how shiny they are, or what color they are. I will make an exception for Shirley Temple. She looked cute in them. No offense to anyone here who likes the way they look. I probably cannot get over the association I have in my mind with doing a job I'd rather not be doing.
