Not odd at all. I am female and have a strong preference for males for therapist, doctors, bosses, mentors, best friends etc etc. The twist is that I am actually bi in terms of my sexual orientation. I have also experienced erotic transference many times in my relationships, feelings that are more driven by the interpersonal situation and role people are in relative to me than the specific person. I do not consider any of this weird, just my personal pattern driven by internal forces.
