Open Question: im confused about my gf. please help.

I am 15 and a half and she is 14 and like well, i was at her house today and we were just hangin out and like we lay down on her bed and like, we were just playing around like wrestling haha and shit, then we settled down took some photos together, and then cuddled. then she started kissing me, and i couldn't breathe, or speak or move my heart was racing, i was SCARED and like dying! it felt like i was dying! so we started making out and it got worse, and the worstttt part of all is that i didnt even enjoy it! i enjoyed hanging out with her but making out i didnt enjoy i was terrified. and it felt REALLY awkward! i hated it, but i swear i have feelings for her! idk lol, thinking about it makes me feel like i did when it happened! well the thing is i really do LOVE her and that was my first time making out, like im so confused, she is actually in love with me for REALS and like she gets SO upset when i joke around about us "breaking up" like and she KNOWS im joking but like, it still bugs her so i dont do it anymore. im just confused, i love her but im afraid because shes the type that based previous relationships on sex and like idk she wants to have sex with me, and i want to with her, but idk so im not gonna do it as far as i can help. im just not wanting to give up a relationship that i LOVE being in, just not the making out part of it. =[
