I dont know why but when i was younger i used to makeout with other girls i did this from age 5 to like 9 or 10 years old i mean now i like boys and not girls but i used to do gay stuff with girls... is it every girl??because all of my friends say the same exact thing.
It's quite normal to do strange stuff with your peers when you're at a young age (from my experience.) It's all part of being curious. Don't worry about it.
