Relationship advice

I know, I know. But I've already spoken to my closest friends about it. 2/3 have never been in a relationship and I need more opinions. I'm in my first relationship ever and with a girl (I'm a girl also). It's been a month now. I'm a very anxious person and handling college, my job and being in a relationship sometimes overwhelms me. I won't lie, I've thought about breaking up but these thoughts go away after a good night's rest.

Anyway, she just sent a text to ask if I'm uncomfortable with kissing cause I'm stiff and sometimes laugh nervously. I said no, but I do feel a bit awkward with long kisses; maybe making out doesn't do that much for me. Then she started asking a bunch of questions. Why? If not that, what else do I want to do with her? And after I said nothing came to mind right now (mind you I'm sitting at the dinner table studying for my exam tomorrow), she said if I IDENTIFY as bi there must be things I want to do with a woman. Then she asked "do you not want me?" And I had a full blown panic attack because I couldn't just say yes. I think I've made her doubt I even like women. Or like her. I do like (and love?) her but I can't imagine having sex yet. I need time and she's ready to give it to me, but what if it's a sign she's not the right one? I feel awful for even doubting in the first place.

What are your thoughts on this? And thanks for reading all the way
