Honey, don't automatically assume that who you're attracted to will change if you discover you're actually internally female.
There are as many different women as there are stars in the sky; everyone is unique, and you don't have to tick all the boxes on a 'checklist of supposed womanliness' to qualify.
I would advise paying more attention to your dreams, as they are often signals from the subconscious. As well as looking into a gender therapist, start to think about your own feelings when you recall the dream you had, about the way you feel when you see yourself as female. Keep sexuality out of it for the moment, because that just confuses things, and think about the other experiences you would go through as a woman, and how that makes you feel inside.
Oh... and welcome to the site. 😉 *hugs*
