Why my KICKBOXING SPARRING friends avoid training with me now when they discover that im gay?

I think it's because they are not comfortable with you being gay, mainly society and media look down on gay guys because they seem Feminine and they are TOO friendly with guys (but this isn't always true!), they probably believe this and well, people can disagree strongly on a lot of things but this is sadly, one of the things where people will disagrees deeply forever. Are they male? If so they might believe if they are still friends with you you might want to date one of them. Make it clear you don't want to date any of them and tell them you are still the person they knew before they discovered your gay. it's hard but try! Tell them to respect you as you respect them. P.S if they aren't respecting you because your gay, then they are not your true friends
