Don't blame you, but at the same time you may be bisexual. If you take a liking to guys as well then it's more likely. Some people say you need to have a sexual experience before it actually counts. ******** that. You know who you love.
Pornography doesn't really tell much. It might turn you on but you don't know the person who you're looking at. Keep that in mind hun. Now if you like a girl who you DO know then you can be sure of it.
Honestly no. A lot of young girls (and boys) tend to be curious about their orientation when they get that sudden rush of hormones that everyone deals with.
The fact of the matter is that most people are a little bisexual.
Though most never act on the bisexualism, a large number of people are attracted to members of the same sex.
You might feel the urge to experiment with other girls, but that's normal. A lot of girls feel the desire to experiment in high school.
Don't worry about it too much; in time, once your hormones settle, you'll know for sure whether you're straight, bisexual, or homosexual.
