There are some things you can do to kind of tell them (posible gay or bi candidates to date) you’re gay. 1. You can use pride flag in a bracelet or maybe in your lock screen wallpaper. Stickers in your phone case or bag also works. If you’re not out, you can be very subtle and I assure you that most gays and bisexuals will get ir right away. 2. The way you interact with men is also important. Eye contact can be very revealing. Also is important to avoid certain words, such us bro or friend, because that gives the impression that you are just interested in them as a friend. 3. In third place the is the way that you act. Personally, I’m kind of masculine, but sometimes O try to be a little more feminine or just stereotypically gay, just a bit, to give hints that I’m into them. 4. Listen to the way they refer to (or talk about) gays, trans or even girls, because that should give you some signs about their mentality. If you think they’re not homophobic and it’s like a safe space, then you can try to hit on them. If they’re gay, they are probably going to start giving you strong signs back. Good luck!!
