I dumped my first boyfriend telling him I was a lesbian. And I did actually like girls, so I then proceeded to date one for about 8 months until I found out she cheated on me. About a year later I found out I was falling for a male friend and apparently it was mutual, we've been together ever since (13 years).

I identified as a lesbian for a while, then bi, now pan. Sexuality is a spectrum and who you are attracted to may or may not change during your whole life. That said it's ok to put a label on yourself if that makes you comfortable, now tho that you can change how you view and label yourself a you please. Life is a journey of discovery.
