Note: I have a good friend who is transgender, so I know a little about the subject.
Hey Joan, I guess if you're transitioning (correct me if I'm wrong) you'd consider yourself to be a girl, rather than a guy. If you're transitioning for the purposes of appearance and femininity alone (without being trangender), then that may not be the case, but I'm under the assumption you're female for the moment.
If you were referring to yourself, even though you may still present as a guy sometimes due to transitioning, it may be fair to approach relationships as a woman in my opinion (and perhaps bringing up you're trans, if you feel that's appropriate). I'm bi so I'm the wrong person to ask really, but it wouldn't necessarily bother me. I think it's easy for me to see this more than others, that genitals don't really make up someone's gender to me. The gender of a brain is the gender of a person.
I guess what I'm trying to say is that, unless you *don't* identify as female, you should probably think of yourself as female and thus the question should be phrased in the way of you being a girl, who has started transitioning and have/will have boobs

Tl;dr: Gender is in the mind. I wouldn't mind if you *were* a guy with breasts (personal preference being bi). You don't have to have surgery to be a woman. Transgender women are born with minds that are compatible with female level of hormones, but born into a body which produces the wrong levels of hormones, for their mind. Transitioning, in the case of being transgender, is not just about physical appearance, it is about the self. So I would also suggest against entering relationships as a guy. (Difference between presenting as a guy and being a guy).
If it's all just for CD purposes and HRT isn't affecting you negatively as it can do (having the wrong hormone levels in your body for a long period of time can mess you up), then by all means go for it!
