I am bi too at least i think i am i do the same thing u do i have a boyfriend but les porn turns me on its wierd but i have fantasised about girls
The reason why you get turned on by watching lesbian porn is because you tend to feel what you are seeing Since there Is a woman it makes us easier to feel every touch.
Wow. You're so young! But I was about 12 as well when I started experimenting with my sexuality so that's totally normal. I'm pansexual, but I also know quite few supposedly straight women who are into lesbian porn. I know u want to think you're not bi but u just might be. U don't have to be romantically interested in a chic to be bi. In my humble opinion if you're sexually turned on by females as well, you're likely bi whether u wanna be or not. But only u know how u truly feel and time will tell what the truth of your attraction may be. Sexuality is a huge, huge grey area, not just black and white like some ppl portray it to be or want it to be. For instance, like I said I'm pansexual but the details are a bit more complicated. I'm slightly more sexually turned on by women (like 60/40) yet way, way more romantically attracted to men. But I've also been turned on by transgender people as well, and I know I would never choose my partner based on biological sex or whether or not they're non binary, etc. Hearts not parts, as I say. Lol
But yes, you're fine. Don't stress it, enjoy it, be gentle with yourself and remember u have the key to your sexuality, no one else. Some ppl just don't realize it because of what they want or don't want to be. Hope that helps. Sorry such a late response!
So give it time and just do what u are comfortable with
