Hi Kris!
Good to have you here

There's nothing for it, just dive right into the forums and keep reading! Only you can decide if you're trans, but we're here to answer all of your questions, help you testing your hypotheses and listen to you vent. For me, reading about others' experiences and discussing my feelings helped me figure things out. At one point I was reading a blog by a trans guy who realized around my age that he was a guy, not a lesbian. And everything he wrote could have been written by me (he and his wife write a blog called firsttimesecondtime). It was as if he had gotten into my head and wrote my story. So here I am.
Possibly, a therapist could help you to figure things out. They can't tell you who you are, but they can help you ask the right questions.
The most important rule, however, is: take your time.
Looking forward to seeing you around
