Is it normal that i have a bf but am unsure of my sexuality

I am 18 and female and have had a BF for 1 month. We have been dating for 2 months and this is my first relationship. He is the first person I have ever kissed.

I am unsure of my sexuality. There are so many things it could be! I highly doubt I am straight/ hetromantic heterosexual. My best guess would be bi or demibi or even biromantic asexual, because I like my current BF and kissing and hugging is nice sometimes(no we have not gone further and atm I don't want to) and I used to be in love with a girl for about 2 years and wanted to kiss her and have a relationship so badly.
Sometimes I wonder if I am in the asexuality spectrum. I could see myself as being Demi-something bc I crave a strong emotional bond, love and support more than physical things. Sometimes I feel like an asexual bc I would definitely not want to have sex w my BF at the moment or go further in any way such as "making out", but I'm not an aromantic bc hey I want romance. Then I question the idea of me being asexual bc when I was in love with a girl I would fantasize about making out and being very intimate. Then I wonder if I am a lesbian bc I have not fantasized abt my BF this way, in fact I only fantasized abt a guy once and I was 13. Then I'm like, how can I be a lesbian? I like by bf's company and its nice when he puts his arm around me and stuff.

Yeahyeahyeahhh I can ramble on and on and onnnnnnn but long story short any feedback would be great but please try not to be mean. I am confused and would love some gentle advice! :)
