So, I've always considered myself into girls, and I've been out as a lesbian for about two or three years. I've been attracted to girls with a few tiny crushes on male friends when I was younger. But then I met my best friend, let's call him R. We're extremely close, and lately, I've found myself becoming extremely confused about my sexuality, and I'm petrified. I think I might be starting to fall for him, and it scares the shit out of me because I don't want to completely reevaluate everything and come out again. He's told me that he's interested in me, but I'm completely scared. I've always felt like I knew that I was a lesbian, but now I just don't know if I'm bisexual, or what I am. Any help out there would be appreciated.
Some people's sexuality is pretty fluid so it's not unheard of for some people to start developing attractions towards another gender. This could be a possibility. You say you've gotten pretty close with him, so it could be that you're attracted to him as a person, not necessarily as a guy. Sorry I can't give you a definitive answer but I hope I helped a bit
