text: I think Oh Velveteen is right. Just tell him that you've noticed him acting a little peculiar lately, and ask him what's up. If he wants to know what you're specifically talking about, you could be honest with him or just tell him that you can't put your finger on it (the second would be my preference). Hopefully he will come clean, IF there is anything to come clean about. Some men are effeminite without being gay, and your friend could be one of those men. \n\nAnyhoo, good luck, and I hope it goes well!
