I used to consider myself straight, and then I got into the sex scene (think kink scene, but with less kinkiness, and the same amount of sex). After some time, I realized that I could be having fun with people of the same gender as me, and boom, suddenly I had no idea what my sexual preferences identified me as. I have fallen in love with people of both typical genders, and also people across the spectrum of sexuality. I like peoples' personalities, not their genitals. Everyone's got holes, and everyone has things to stick in them. If you need some more holes or some better things to put in them, there's a whole industry waiting to help you find a solution to that problem.

> Sexual fluidity is also not the same thing as bisexuality, which is another sexual orientation.

This kind of thing triggers me now. Sexuality is not a category. It's the relationships you have. If we want to categorize this, then there are effectively an infinite number of sexualities. How would you categorize me? I am currently in a relationship with a person of the opposite gender, but we both enjoy having sex with people of all kinds. I have fallen in love with people of all kinds. Does that make me bisexual? Pansexual? Sapiosexual? An adventurous asexual? Sexually fluid? My point is that it doesn't matter! It is what it is.

Go experiment and learn about yourself. You might be surprised at what you find

Edit: I would also like to add that you are never too old to experiment with this. And! The "sex scene" is probably the safest place to have sex that I can think of because everyone that I've met in it is open and honest and respectful
