Confused about my sexuality

So this is the first time I’m actually saying or in this case writing it all down. I am 18 and I have had many failed relationships with guys. But that is completely normal because... well I’m only 18 haha. But recently I’ve been finding women more attractive. I get that having “women crushes” or “female celebrity crushes” are a thing and all but like when I see a girl on Instagram or when I am ringing them up for an item in the store I work at, I can’t help but have thoughts. They aren’t always dirty thoughts too. Sometimes I just imagine what it would be like to date a girl. But I’m too scared to talk to someone about it. I feel like I should feel ashamed or embarrassed. But I also like men,

I just can’t seem to shake those thoughts about dating a women. I don’t want to talk to anyone about it until I figure out my sexuality. Thank you for listening to my unimportant problem I am currently facing ✌🏼
