Regardless of my most recent SOs' orientation, I didn't feel right going through transition while maintaining sexual relations from the past.
I have no doubt that every one of these relationships blinded me from my problem, being with them made me feel happier and I didn't spend much time thinking about it.
Cross-dressing around them was rare and more of a joke although they probably had a better idea of what I really was, than I did at the time. I managed to meet women who were very open-minded, and so was able to be open about my decision. What shocked me more was the admissions from some of the friends that I told, that they were secretly bi or gay.
