What were you hoping for GenCat when you mentioned to T that there was a "possibility" of your being lesbian? If you do not know/are not sure, I would explore for yourself what you feel? I don't think another person can know for you, they only have their opinion, based on what their interaction/relationship with you says to them. I don't know that sexual attraction/orientation is "decided" or permanent, necessarily. I look at sexual attraction/orientation more of a continuum and the factors influencing how we feel is a complicated mix like other developmental experiences?
