I've only ever seriously dated men in the past and I think I would probably have identified as "straight" but felt a little hinky about it - since I have had brief flirtations with women. But now there's a woman who I think I may have a crush on? I don't know if she's interested in dating women either, but if I decided to approach it - what would be a tactful way?

(I'd like to be clear that I'm not looking to 'experiment' but rather that I find myself attracted to this specific individual.)
