I’m sure you don’t believe me either, but when my friend came out in his early 20s I went with him to gay bars like a half dozen times to show support. Every time I would get compliments, and it was really a pleasant exchange like this except instead of girlfriend being around I let them know I was there to help a friend feel comfortable.
Two times they bought me a drink, and I was never made to feel unwelcome since I was there to be supportive.
Plus the compliments really did make me feel good about myself.
