Am I a lesbian or straight? Or is this hormones?

I'm a 17 yr old female, I'm sexually attracted to malEs I can imagine dating them and having sex with them. I'm emottionaly attracted to girls, usually Women who I admire such as friends or celebrities such as beyonce. My type of guy is a rugby player pref Irish lol. I have had sex dreams with both sexes but with girls I only go as far as kissing and it's usually not me kissing them but with guys I go all the way. I have never had sex been in love nor kissed a girl, I understand about hormones as I usually feel like this around my period time but I when I feel like this. I was wondering if it's normal or whether I am gay. Thanks in advance
