Frankly, I do get approached by gay men and get IOI’s from them often. As
@AmsterdamAssassin said, take it as a compliment. If you’re well put together and in shape in your 40’s and 50’s it’s natural because most men in that age group who are, are gay.
Often the guy is well put together and can be the best wingman ever, why? Because good looking heterosexual women befriend them because they’re not getting hit on by them, this opens the door to you when you’re introduced, which you will be. As long as you’re clear you’re playing for the home team you might have a great conversation and spark a friendship. Most times they respect your stance and it’s like any other conversation.
