Im (m) am going on a Date with a woman but im not sure if im into them. How can I communicate my insecurity so no one gets disappointed ?

I met a girl at a party and I was very overwhelmed when she showed interest in me. She's a friend of friends and they said to me afterwards that she's down to get to know me (she wants a sex partner) and that I should text her. I did and we will meet for a drink. The thing is, they don’t know that I’m unsure if I like women sexually. I have a girlfriend but no sex and I know I like men. I would be open to trying stuff but I’m not sure how to communicate that I have no idea what I’m doing, dont what I like and Im unsure If I would be into her. I know that I should be upfront about it but I’m afraid to open up to her and to my friends as well. What do I say? I feel like my friends want me to fancy her but that just creates pressure for me
