I've been attracted to women since I was 12 years old and I had only been attracted to women till I was 15 then I started liking men as well. I was very happy because I thought my liking girls was just a phase that would eventually go away, but it didn't. I'm 22 now and still very attracted women as well as men. Only now I feel likes somethings changed when every I meet a woman who I'm attracted to I feel like I can't breath and theres a weight on my chest.
In a number of scientific studies most females were found much more likely to be exclusively bisexual than most males and like bisexual males, females can lean more towards one end of the scale than the other. The ends of the scale being exclusively heterosexual and exclusively homosexual with levels of bisexual attraction in between. You can find The Kinsey Scale Test online which is a series of questions you answer that may help you determine which end of the scale you lean towards. HTH
Did it change? Perhaps you just discovered you liked men later on? For me it was the other way around. I first had a heterosexual phase . I thought my feelings for women would go away too, but they didn't .
Sexuality is fluid and it's pretty rare to have a rigid sexuality. I have a very rigid sexuality personally, but it's definitely not the norm.
I only started being attracted to girls when I was fourteen (I had low-key crushes on boys before then) so yeah, its possible.
I'm not trying to blow anything up here, but, you like girls...you also like girls...you hang out with guys but you like girls... Girl, with this evidence...
I 100% believe that sexuality is flyid. I have always liked women, but have been in relationships with men. Over the past few years, I am finding that I am no longer attracted to men. So I dont think your sexuality " changed", I think it may just be fluid.
I've never felt any attraction to women that I remember. I was so bothered by it in my teen years (due to prevalent homophobia where I grew up) that I tried to "change" my sexuality on my own but it never worked. I'm 29 now and still only feel attracted towards men. In light of that I feel that sexuality really doesn't change. From what you're describing it could be that you're bisexual but lean towards women more than men. From my understanding, it's possible for bisexuals to feel more attracted to one sex while still having some minor attraction to the other. I guess in that way sexuality can be more fluid with bisexuals than people who identify as strictly straight or gay.
