Just confused

So since people I know don’t follow me on here I can pretty much say whatever I want. I’m bi I have my first girlfriend things like that. I’ve always been pretty girly and things like that but lately I’ve been wanting to wear things that aren’t so girls like looser pants and sports bras instead of push up bras and big t shirts instead of the cropped shirts I usually wear. I feel confident but I get nervous about what people will say and what they will think. I just feel like I’m not sure who I am completely. it’s so fucking weird. I don’t really know what I want people to say I just wanted to say it
