I consider myself straight. I don't like grown up men. But I do like grown up women. I am a teenager (about to turn 18) and on my observations so far it's a normal phase of development to be a bisexual boy or girl, but...
I sometimes listen to Taylor Swift. Especially, the song
makes me giggle a lot. Whenever I daydream, I dream of usually daydream about the good, flirtatious moments I had with my 'friends.' I may be locked up in my house and have poor social skills, but I look sort of manly. Now to to brag or anything but I am around 5'9, weight 100kg (but the hair on my body covers it up) and look pretty good looking sometimes when I dress rightly and use perfumes, and especially neat after recent hair cut.
So yes I find thinking myself more about guys than girls. Especially the guys that look cute (as opposed to those that look like me)... Do I have gender dysphoria or something? All of them must be thin (not too thin), have appropriate height, etc.
