I guess the first question is: who is it that you want acceptance from? Those around you, or yourself?
I think that once you can accept yourself, and be comfortable with who you are and how you live your life, then it will be easier for others to accept you.
I've often had similar thoughts about my appearance making a difference to whether I'll be attractive to my partner, and even thought about the 'butch' thing. But that word, I think, seems to fit far more than just the way someone looks. It covers attitude, approach to life, thoughts, speech, the way you express yourself, the way you feel about things in your life.
And whilst it's possible for someone to appear one way, that doesn't make them essentially the same way on an emotional and spiritual level. You can look like an A1 Abrams Battle Tank (lord knows, I do) but still find beauty in the smallest flower and cry at a sad movie. Butch is a state of mind, is what I guess I'm trying to say.
In an ideal world, a prospectve partner would be able to see past what lies on the surface, and be able to penetrate to the heart, and learn what you're really all about. However, that's in an ideal world. Superficiality is something that's very real. Which is unfortunate.
There are all kinds of people in this world, though. And the ones that you form the deepest connections with are the ones that see you for who you are. You're a woman inside, and that's what counts. When it comes to feelings, emotions, love, expression... you're all female. And that can't be fully hidden by anything, even your own desires to do so.
I'm sure you'll find someone who sees you for who you are, and not for how you think you look.
I wish you luck and that you find some peace. *hugs*
