This question is for cis- people (people who are not transsexual) only. Some people believe that cis - people are divided into two groups. The first group strongly identify as their birth gender (eg was born a man and strongly identifies as male) and would feel wrong and creeped out by the idea of changing gender (eg a man who is freaked out by the thought of waking up in a woman's body). The second group have minimal gender identity, and identify with their birth gender only because they see no reason to go through the hassle and social stigma of transitioning (eg a man who would be happy as either a man or a woman, but since they're a man, they stay a man).
