Today was the first day that I checked "Bisexual" on an official form. It was really scary, and took me about a minute to actually decide whether or not I was going to do it. It was scary.
Congrats! This is an important step in becoming more publically comfortable with who you are and that's awesome! (!)
I felt the same as I entered my real gender it was so liberating! I felt like I was finally being honest with myself
