Omg what should I do????

So recently (Friday) I got with this guy I’m still in the stage of figuring out my sexuality I think I’m lesbian because today he held my hand and hugged me but it felt super awkward cause I couldn’t possibly kiss or do anything physical besides hold hands and hug anything else makes me sick but girls I could do anything and be just fine but guys hell to the no?? But I don’t have the balls to do it so I’m so scared to break up with him plus he knows where I live and my phone # he wants to hang out this weekend but I don’t wanna kiss or anything cause it’ll make me sick also I talked to my lesbian friend she said I could think a guy is cute without wanting to do anything
