Like ive never been attracted to guys and i dont want to be with a guy at all but ive tried putting like stuff like a shaving cream can, im still a teen but i havent even done insertion in over a year, could it have been curiosity or a phase?
You answered your own question.
If you are not attracted to men and don't want to be with them you are not gay, it's as simple as that.
It was probably just a phase and it;s okay to experiment with your body as long as you don't injure yourself. Being gay isn't a bad thing it;s who you are but you are straight if you are not attracted to the same sex.
