Writing Realistic Opposite-Gender Characters

When I first started out writing I wrote in my protagonist's POV, Audrey (a girl) and found it easier. I felt afraid to write in a male perspective and I felt that I wouldn't be able to do the justice it deserved, but when I started a new story I thought "why not?" so I tried it out and wow, I absolutely love it! My readers seem to appreciate it too :)

It's actually a lot easier for me to write from a male's perspective than a female's. I think it may be that 1. most of the fiction I read is written by a man, from the POV of a man, and/or 2. I grew up in a house where both my father and brother were very open with talking about how they felt, sharing experiences and the like, so I could easily see into the mind of a male.
Not to mention, I just don't like writing from the point of view of a girl. It seems almost foreign to me.

I generally write in third person from a male character's perspective because that's what's more interesting to me. I live my life every day in a female mindset, so that's a little boring for me to write. Admittedly, I don't have a lot of experience with men since I grew up without a father and the only male in my life was my older brother, who's a whopping twelve years older than me, but according to the guys in my writing classes, I do a pretty good job of channeling the male mindset.

All in all, I don't think there are a ton of differences between men and women. I think humans are humans, and I don't think it helps anything seem more realistic to try to fit a male character into society's stereotype of how a male should act and what he should like, and the same holds true for women. I believe people are people, and as long as you feel like you know a character, gender shouldn't matter.

While I am incredibly girly when it comes to fashion, makeup, hair, and all that good stuff, as far as relationships go, I feel like I lean more towards the behaviors and ideals that are stereotypically male. I also love sports, so that doesn't hurt either. I like to joke that I'm the most girly and the most manly person I know

I don't mind writing them as long as I'm not writing in their point of view. If it's first person from a boy's POV, all I can think about the whole time is "my junk is getting scrunched up" or something along those lines I'm mature for my age.
