I think it's pretty awesome that you are able to look at your sexual feelings and come to a revelation about them at all! It does sound to me like you may be on the verge of re-evaluating the way you label/define your sexuality, and the most important thing I can tell you about that is this: THAT'S OKAY!! As long as such a re-defining comes from within yourself and is all ABOUT yourself, and not about others (i.e. you're not trying to change for other people, or to "make life easier") the process you are going through can be very healthy and good for self-understanding. Your thoughts on the matter make perfect sense to me--I actually went through kind of the opposite thought process, where I believed that I might be attracted to women as well as men because women were "safer." After taking a good long look at my feelings, though, I realized that, yep, I'm just attracted to both genders. ^.^

Good luck and take care!
