Sarah, have you ever tried sex with another girl? You should experiment and see if you like it. Start off slow
Can someone help: I'm a 16 year old girl who has imagined being with another girl. What should I do?
That's natural for your age, don't stress yourself out over labels, your sexual orientation is constantly changing for you, especially at sixteen. You don't have to do anything you don't want to, but I'd say go for it :)
Relax; because this is common. Plus, the more forbidden you make it, the more you're going to dream and visualize it. Imagining gay and lesbian scenarios, even sex fantasies, does not make your lesbian or gay.
However, acting upon them in real life with an actual, real, breathing, live human of the same sex you are, more than once? Alright. NOW you can begin suspecting you might possibly be gay.
