Is it possible to want to be the opposite gender after adolescence?

Uh, I could be wrong, but as far as I'm aware, Gender dysphoria can happen at... Well, any age, just USUALLY as a child. I discovered my sexuality/romanticality at 15, and my gender at 16. I still have some dysphoria, but I'm getting over it. I don't think you're so different from a lot of us. Sure, many know from a young age; maybe since they were born, even. But some if us don't. And that's just fine. you can explore all options for yourself. Hope that helps.

 

For most people it usually manifest with the inset of puberty, but for many people that isn't the case. Sometimes dysphoria is repressed or not there at all till something , like drag for some people, triggers it.

Think bout it, there are people over 40 only just now realizing it all.
I was reading the blog of one guy (think its called tranifesto). He was 45-ish when he told his his shrink that he had days where he often felt genderless. Before then he presented as a girly girl. He always had that sense of being off or wrong but never connected it to his gender till talking about it with someone.

 

I'm 27 and only now am I coming to terms with that I'm a guy not a girl. It took a lot, I mean, been a cis girl all those years even if I was more tomboyish. But to finally accept with myself that I wasn't born the right gender?
Maybe you have felt this way for awhile and are just now realizing it. Maybe you've been more gender fluid and are finally finding you want to choose a gender that better adjust to your mind set. There is also a saying that every 7 years or bodies go through a change, maybe this is your change and its just a big one.

Whatever the reason, you can discover your the wrong gender later in life and be diagnosed with gender dysphoria at any age.
There are things you can do aswell;

Try doing buying makeup and applying it at home. If your not ready to go out in it, than try it around at home when you don't plan on going out. Right now is the perfect time to buy a wig and wear it, or buy women's clothing and try wearing it as well. I found it really exciting to buy my first outfit as a man. Think of what you'd want your name to be as a girl. Think of how it would be to have a relationship with someone as a girl.
Read about surgeries or Estrogen hormone therapy and see if its something you'd actually be willing to do when and if you were ready to commit to it.

Honestly, I didn't realize how much I wanted and loved being a guy, till I actually passed as one and was called 'sir'.

And hey! Who knows. Maybe you just want to dress like a girl and wear makeup, but still want to be a guy. Theres no shame in looking good and being in drag.

If you want someone to talk to you can message me if you want. Good luck on discovering yourself.

 

Like others said, it varies.

But I was definitely one of those who got the "wouldn't it be better to be a girl" thoughts after adolescence. I guess it kicked in harder sort of as a response to puberty that was working to make me look and sound more actively male. Over the years I steadily realized how much that was really bothering me.

 

People come into their personal identities at all sorts of different stages in life. Some people know their whole lives that they're trans, and some people don't know until they're in their sixties. It's actually very common for it to surface around adolescence because during puberty you start to develop your secondary sex characteristics and you become interested in dating, and all that tuff is at the forefront of your attention.

 

Of course, I'm 17 and didn't really start realizing that I had problems with being a guy and wanted to be female until earlier this year, it happens at a different time for everyone; and it's fine if it's only happening now for you.

 

Gender dysphoria/general confusion can occur at any age.
