Sociologists have documented that men and women can indeed just be friends and that there are actually benefits that come with cross-sex friendships — like learning from the other side how to best attract a mate — that you cant get from same-sex friendships.

Can you be close friends with the opposite gender?

Life isnt like an episode of Friends; not all men and women are attracted to one another. There are differences between male and female friendships you should know, but to think that it is impossible to have opposite sex friendships is just a ridiculous notion.

Is it a red flag if a guy has a lot of female friends?

When a man is involved with a lot of female friends it can also be a warning sign that he is not a man who is ready for a relationship. I know many men who have a ton of female friends who havent been in a committed relationship in years or ever.
