ime going on hrt gives you more space to play with gender non-conformity/expression than never having been on it. look at the side effects, if there are any you absolutely don’t want and couldnt cope (an ex. of coping might look like shaving/laser for body hair u don’t like) with then maybe pump the breaks. if there are some you want and you’re mostly positive/neutral on the rest then go for it. you can always try it and quit if it’s not for you. every week is a chance for self-reflection.
