A straight man does not really have issue with a beautiful transwoman with her penis, neither he liked her penis specially, but accept it as part of her. Only a bio male may possibly like her penis. What concerned me is how to fit in the topic as part of the love confession, with suitable words. I do not view this as something to be proud of, but is part of the pain of growing up, which he should be aware (that I'm the one suffering the pain) and should have empathy for if he loved me, and not that he has the reason to reject me as though it is my fault (for transitioning). At least if he can't accept he doesn't have reason to view it as my fault but have strong empathy for me, and regret the fact that he didn't truly love me enough to be able to accept me for what I am. I want the words that is able to generate that understanding and feelings of something like:
"It is only for the love of man like you that is the reason I have became a woman."
"I want to be the beautiful woman for man like you, you are the man of my dream, you are the reason I have became a woman."
"Man like you is the reason I have lived for, you are the reason I have became a woman."
I am looking for more good example of sentences like this to break the ice romantically to finally said the truth to him by adding something like:
"I am not a true woman but because you are the man I loved, I want to be the true and better woman in your life".
I try to avoid using the medical terms for pre-op, transwoman and so on, as these will be having opposite effect to those romantic feelings generated from the sweet and loving words.
