Hi Belle
that's a good thing to do, honesty is everything in a relation, it will set you free, no hiding, no excuses for periods and so on, and you said he loves you so there will be no change in his feelings except that now he can trust you even more.
After all, you're a beautifull young woman with a bit of bad luck born in the wrong gender and he felt in love with that woman.
There is no need to go stealth for your bf.
Your whole life you where playing a role, being the man that you didn't have been, so don't change it into an other role.
you're just wonderfull the way you are and your past is a part of you, there is nothing we can do about that, nobody can change the past.
So, we are Tgirls but we can be proud because we did what we had to do to forfull our dreams and there are a lot of people who had great plans and dreams and they have done nothing with it, we are different and steadfast, isn't it?
good luck telling him
love
annette
