I as think more about the "external influences," and Susan R. summed them up perfectly, they do exert influence going the other way also. My experience coming out is that about 75% of the people are totally shocked. We hide being transgender most from the people we are most afraid to loose or hurt. Our family and close friends. If things go well, these close people move towards supporting our decision to live openly. Then those external influence actually move from stopping, or slowing, transition to pushing you towards it. I personally found the in-between, or part time, very challenging. Some people were expected to call me Joe and others Jane. This was really hard on my family, especially my spouse. Sometimes I was a husband, and sometimes a wife. The pronouns and name flipping were super challenging. It has been much easier for my family for me to be just one gender, and not trying to live as both. So I feel there is some pressure to "just transition."
