Wanting to be trans and feeling guilty

I (amab 23) am heavily questioning my gender. I feel like I almost want to be transgender. Like I took pictures of myself in a dress with makeup on and I got butterflies in my stomach and my immediate thought after was “oh you just want to be feeling that way and your brain made you react like that”

i feel like I want to be trans but don’t know if I am and every time I have the thought i think you myself “oh you just want to feel like that and it’s for all the wrong reasons”

Also I just started therapy (for general purposes and for gender stuff) with someone who is good with lgbtqia+ individuals and when telling people about it I almost feel guilty and weird because then if I’m not trans I made a big deal about nothing in the en.

Any advice or has anyone felt this way?
