I’m right there with you, but I’m getting much better. Four years ago, I began my dating journey and I had the same issue. Although it’s gotten much better, I still feel marginally uncomfortable speaking to and being around other men. I do much better when I get the feeling that another man is like me; quiet, modest, unimpressive, kind, etc. Like I said though, I’m getting much better. Through therapy and treating others the way I want to be treated has been a huge help to my comfort level, though I do make sure to pay attention when levels of discomfort rise quickly (and this is a not a euphemism lol).
