Making male friends isn't that difficult.
Making male friends that can help you with forming a social circle capable of arranging dates for you is difficult.
I have some male friends. I could probably spend more time on the male friends part of my life, but because dating/sex stuff takes up so much time, I don't spend a lot of time on forming new male friendships. My current male friends are all married men who aren't concerned with spending a lot of time with me. They are busy with their houses, dogs, and some are starting to have children. It's not personal, that's just how married men tend to be. Married men are notorious for starving male friendships with unmarried men, although they are probably ok at maintaining friendships with other married men.
An apartment complex is a good place to become friends with other men. If your apartment complex is 100+ units, I think there's a good chance that you can find a male friend.
You might be able to find a male friend in a co-ed sports league. However, a lot of men in co-ed sports leagues are trying to get their penises wet, so that might not be the ideal place to focus on making a male friend.
If you want to make male friends, focus on environments where women aren't too present. Once women are present, men and the male thirst are focused on trying to get with the women.
