Sexuality

So i’ve been trying to decide if I am bisexual or maybe straight with a small attraction to females. I am a teenage girl who has always considered herself as straight however I have kissed more girls than boys and have had more sexual encounters with females. I have only been in relationships with males but I wouldn’t mind being in a relationship with a female. Long term I can see myself marrying a boy but not a girl. I’m also scared of coming out especially since I an already in a relationship at the moment. What do you guys think? (Sorry i’m gonna post this anonymously only because i’m currently in the closet and not comfortable with my sexuality and very confused.)
