I actually thought I'd addressed this issue in other places on my site.  However, while looking up what I have written, I see I've talked about how sexual orientation has nothing to do with gender identity but have been somewhat vague about myself.  Before I answer, I'd like to state, that this question is every bit as impolite as asking anyone about their sexual history or practices. The only reason I'm going to talk about it, is that one goal of this site is to educate.

In the past, I had always identified as a heterosexual male.  However, in reading about and talking to transgender people, I have come to find out that while some people’s sexual orientation, i.e., who they’re attracted to, stays the same as it always was, other people’s attractions may change over time.

So, part of my journey in expressing myself will be to determine what/who I am looking for in a relationship. That being said, however, I do not want a relationship right now, as I'd like to be comfortable with my 'new' body and situation before involving someone else.  I'm not sure how I'll feel after GRS.  So, as I work toward transitioning completely, I’m sort of letting the feelings come to me (or not), about wanting to be with women or with men. 

Assuming that I want to pursue a relationship in the future, maybe it will just be heterosexual (meaning with men of course) or I'll just be a lesbian.  All I can say is I will be exploring my feelings about this, and can't possibly tell you how I'll feel in a year and half and being post op.
