I don't often come to this Forum or check through all the posts, so it has taken a while to get to this one.
I want to take you back to a comment KaraBlut made where they mentioned "massage" and I think you misinterpreted it as "message". If you can find a male masseur and experience a man's touch on your body, even though it is not as a sexual experience, it might help in taking a small step towards experiencing a little of what you want in that direction to break the ice. Although masseurs don't generally provide erotic massage as it can be interpreted as prostitution or it is risky for a masseur to explore with a client who might be offended and take legal action, there might be some who may ask a client who gets a physical response during the massage if they would like them to take care of it and you could get lucky; and if not, then you still get a massage and the experience of a man's touch.
There are also groups such as Body Electric School
https://bodyelectric.org/ which runs workshops to teach men and women more about their bodies and sensuality where you might get to meet other men in a similar position to yourself, whilst gaining hands-on education that is overlooked in society generally.
These may help you move forward a little even if not finding the man of your dreams.
I wish I could help you, but I'm not even in the same country. My own experience has been fairly limited and restricted because of health issues, but I also found it difficult to find the sort of interaction I wanted, which was a kind of occasional friends with benefits, particularly because I wanted to get to know someone before becoming vulnerable with sex, but could not sustain an ongoing full-on relationship. The problem was that most guys I met wanted more sex than I did, starting immediately, or they were only interested in a one-time deal; whilst one guy planned our lives out together on the first date and I wasn't even sure I liked him yet. The biggest issue for me was fear and a lack of confidence I could say no once I had started, if it turned badly. Another issue was that I have never found sexual expression rewarding and what passes as an orgasm not worth the effort, which kind of kills any interest in pursuing it, although I expect my own experience is kinda rare.
As for bars, be careful someone doesn't spike your drink and you get sex, but can't remember anything about it.
Good luck.
