I have yet to decide whether transitioning is or isn't a damnable offence, and if it isn't, then I would have to look into having a relationship with which sex is damnable bar penance.
So far, it seems that transitioning and having relationships with guys is perfectly okay. However, I have a lot of time left before I can make the decision in finality (and I will be transitioning and being with guys in the meantime, for as long as it seems correct), in all likelihood, and I will keep an open heart even after things are decided.
Why I think transitioning is okay is the result of a recent experience. I lived as male for three days as an experiment... and the results were that living as male would be a farce at best. I acted very femininely for a guy, and without doubt I would always be thought of as gay if I were male. Additionally, I found it very difficult to keep my voice down in guy levels - it hurt my throat and was a conscious act every time I used it. In no way do I make a proper man, or even a boy - I could pass as one, sure, but that couldn't change the fact that I just don't act like one, or think like one.
It's been a difficult process coming to terms with my androgynous appearance. Certainly, living as male would be easier, and I will likely run more experiments, but for the time being I will just be myself - classification is unnecessary. I will simply exist, and be led wherever my heart goes.
I am thankful that you have found your path, and I congratulate you. I hope that my journey will be expedient so I can feel a similar revelation in due time.
