Hey hey, welcome to the forum! Gay FTM here

I know what you mean about feeling good because guys were attracted to you. I went through a stage at one point of wearing shirts and things that showed off my chest because it got me possitive attention from guys, but at the same time it made me feel a lot more uncomfortable, so it didn't last long. I used to see a dress in a store that I really loved, would buy it and wear it for a day, and spend the whole day just feeling completely wrong and out of place, I got so insecure and worried about what everyone thought of me, that I would then put the dress away and never wear it again. That was before I even realised I was trans.
I first realised there was something up when I started reading guy on guy fanfiction, and found I couldn't read straight coupling. I thought I was just weird until one day I blurted out 'I wish I was a guy, so I could be gay' to one of my friends. She and the others all laughed while I stood there looking like a stunned mullet as I realised how true the reflex statement was.
Realising something like this about yourself takes time, it took me several years to get over the internalised 'You're just a damn tomboy!' phase. It's awesome you have a friend going through the same stuff, I'm sure you'll find many more on here
