Gender change spell

Can someone please help me with a spell for this? I can’t find any that work

You can't change your biological sex with magick.

If you feel uncomfortable with your biological sex and want to look into transitioning, though, you could discuss options with a counselor. There are counselors who specialize in gender and transitioning. Even if you aren't able to physically transition for whatever reason (finances, age, etc), you could still socially transition, such as changing your name and pronouns -- provided you feel like you're in a safe environment to do so, that is. You can also change your appearance with clothing and makeup -- for example, if you were assigned male at birth but identify as female, you can wear makeup and grow out your hair to have a more feminine look, and if you identify as male, you can wear loose shirts and sport bras to flatten your chest and cut your hair (there are other options, those are just examples).

I'm not sure if you're asking because of that or just because you're curious as to what it would be like, but I just thought I'd mention that option in case that's what you're looking for.

Maybe a spell to change my behavior and how people see me?

You do not need a spell to change your behavior, you just simply need to make it a point to do so and stick with it.

If you want people to see you differently, then change how you present yourself.

Behavior is an interesting thing to mention.

If you want to change your behavior because you want to grow into a different person, then think about what kind of person you want to be, and then simply act according to those ideas. Eventually, you will just grow into it. It just takes practice and dedication, as said above.

If you are trying to adjust your behavior to match a certain gender, then keep in mind that gender's don't inherently have specific behaviors. They may have been trained to think a certain way socially, but who a person is is just that. Each person has masculine and feminine traits, regardless of their gender, and there are just as many feminine men as there are masculine women, and vice versa. It's really all about the person you want to become.

As far as a spell to change your gender, as was said before, there are no spells that can change your physical features. You may try a glamour spell to make you appear more masculine or feminine to others, but if you would really like to change sexes, you should speak to a counselor or a doctor about the process of physically doing so.
