we are all the sum of our experiences and our past. that being said who we are is not always who we were. this applies to everyone no matter their gender or preferences. speaking purely for my self if I were dating a woman and found out she used to be a man, I seriously would have no problem with that (providing of course I found out by her telling me and not finding out from other means. shows she is not hiding anything.) as for a pre op woman, it would largely depend on the person, and the relationship. I personally feel that if two people cared enough about each other accommodations can be made to the mutual support of both parties what accommodations get made again depends on the couple, and their relationship. I am a straight heterosexual male, and I have met someone who is a transsexual. pre op, or post op, I don't know, and at this point in time I really don't need to know. and because I do have a somewhat romantic view of her it wouldn't matter because accommodations could and would be made.
