Agh, this is a tough one. I should probably start off by saying I am gay, which immediately brings tons of stereotypes into the mix, but I'm not very feminine. I'm a mix honestly. Growing up I was definitely more feminine, but a while ago I noticed I'm slowly becoming more masculine, especially as I hang out with more guys. I'm kind of balancing out now, I'm not super masculine and I'm not super feminine. People are literally confused when they meet me, especially lately. I have an "average male voice" i guess you could say. I don't act or seem flamboyant or act to talk feminine, but I get people telling me often that I am "definitely in touch with my feminine side". But I've also been told that's a huge turn on to girls.
I'm assuming this came up from being a little self-conscious about it, I was too, I grew up in a christian conservative home who were very against homosexuality and I thought I was extremely obvious. Really, if you are self-conscious about it, don't worry. Depending on how young you are, you could almost change/ grow into a more masculine version of yourself. You're a dude, regardless of how you "act". Some tips if you do want to feel a little more masculine, would be work out. That's by far the biggest piece of advice I could offer. It's uncomfortable for the first week or two, but it gets much better. That will actually increase testosterone. Another huge thing would be jsut get comfortable with yourself, inside and out. Confidence is one of the most attractive things to anyone, and it can be especially hard when you don't want to seem feminine, I know I've been there. The last thing would just make sure you eat a rounded and healthy diet, and get plenty of sleep and rest/ relaxation time.
All in all, I am definitely in touch with my feminine side, but I'm not "feminine" if that makes sense. Most people are surprised when I do tell them I'm gay.
