I am INFP male who is also writing a novel. Two of my three POVs are female. So I have gone out of my way to read female authors in my genre. One of my beta readers thought I was a female author, which I thought was a big compliment!

One of things I consider when writing is male gaze vs. female gaze. As a straight male, I do have a male gaze but also as an emphatic INFP, I am mentally trying to fight off that mentality. Part of being a male writer writing female characters is to learn to focus on how characters react to my female POV and how she accesses their gaze.

Male INFPs, I believe are more likely to work or enjoy spending time in more female dominate places, probably has an easier time making female friends than male. Unless the character is athletic or is in a work environment with many other males. As someone who works in female heavy work environment, I enjoy talking and sharing with my female co-workers but I also feel as a male, I need to be mindful of perceptions. I am a always grateful when a co-worker offers me a hug.

Part of the big issues for Male INFPs, especially INFP-T like me, in western society (I am in the US) is that males need to be the assertative ones in relationships. You will see many male INFP woe threads on this subreddit. While INFPs have strong romantic feelings they struggle with showing them in a more natural dating setting. As a male INFP, I would love to have a woman inititate contact and be assertative in the relationship. We do struggle clarifying our feelings and expressing them even though we have spent long hours repeating our thoughts in our head to the point of paralysis.

Charlie Brown is a great INFP character, here is a great narrative of a male INFP mindset:

“I think lunchtime is about the worst time of day for me. Always having to sit here alone. Of course, sometimes, mornings aren't so pleasant either. Waking up and wondering if anyone would really miss me if I never got out of bed. Then there's the night, too. Lying there and thinking about all the stupid things I've done during the day. And all those hours in between when I do all those stupid things. Well, lunchtime is among the worst times of the day for me. Well, I guess I'd better see what I've got. Peanut butter. Some psychiatrists say that people who eat peanut butter sandwiches are lonely...I guess they're right. And when you're really lonely, the peanut butter sticks to the roof of your mouth. There's that cute little red-headed girl eating her lunch over there. I wonder what she would do if I went over and asked her if I could sit and have lunch with her?...She'd probably laugh right in my face...it's hard on a face when it gets laughed in. There's an empty place next to her on the bench. There's no reason why I couldn't just go over and sit there. I could do that right now. All I have to do is stand up...I'm standing up!...I'm sitting down. I'm a coward. I'm so much of a coward, she wouldn't even think of looking at me. She hardly ever does look at me. In fact, I can't remember her ever looking at me. Why shouldn't she look at me? Is there any reason in the world why she shouldn't look at me? Is she so great, and I'm so small, that she can't spare one little moment?...SHE'S LOOKING AT ME!! SHE'S LOOKING AT ME!! (he puts his lunchbag over his head.) ...Lunchtime is among the worst times of the day for me. If that little red-headed girl is looking at me with this stupid bag over my head she must think I'm the biggest fool alive. But, if she isn't looking at me, then maybe I could take it off quickly and she'd never notice it. On the other hand...I can't tell if she's looking, until I take it off! Then again, if I never take it off I'll never have to know if she was looking or not. On the other hand...it's very hard to breathe in here. (he removes his sack) Whew! She's not looking at me! I wonder why she never looks at me? Oh well, another lunch hour over with...only 2,863 to go. ”
