For me, being curious or even occasionally mm interaction sexually does not change your orientation. But, how everyone views this is different. For example, if a guy says he is straight but bi-curious it doesn't make him "less" str8. I'm curious what it would be like to fly a plane but that doesn't make me a pilot. Even if I take a few lessons and grab the stick. . .still not a pilot. I understand "labels" with two meanings. One is Just sexual. You enjoy getting off with someone of the same sex. There is some sort of physical, sexual enjoyment but not necessarily emotional connection. The other meaning is the emotional, relationship aspect of sexuality. I separate sex from love. Sex is a pleasurable physical act, nothing more. I am technically bi because I have physical, sexual attractions to women. Now, I rarely if ever have a love like emotional bond with women. This is something that I typically feel Just with men. This shifts me to self identify as gay. Even if I have sex with a women I am gay. I use the relationship based label because it is less confusing socially. I found women heard mixed signals from bi. Like there was a chance we would fall in love and marry. Not the case for me, bi means only sex.
I tend to ignore the social stigma and fight over sex, labels, and sexuality. I think of this logically just like Any other sexual pleasure. Some people enjoy vibrators some don't, some enjoy teeth on their cock others no way. What feels good and gets you off are actions and behaviors not orientation. Orientation, at least for me, is established by emotional and social bonding. But again, my personal opinions are just That, my opinion. Everyone sees this differently and another persons label should never pigeon hole your identity.
