What would you do

My name is Re11 I'm 20 years old 5" 10' tall. Lets being with my story.

I'm currently studying in college but still I'm a virgin. It's not like i had no chances of sex i did but....i couldn't control myself. I have a Gf named Elsa. She is 5" 3' and very cute and innocent. All friends are jealous of me to have such a cute Gf. It was with her when I tried having sex I cummed as soon as my dick touched her pussy. I was really embarrassed and she was disappointed. I tried to explain it to her that it was because she was so hot that I cummed so early but she was very dissatisfied with what I had to offer. I felt pretty useless. After that she left and didn't call me the whole day. I called her next day but she avoided my calls. I was really scared of why she was acting like this. So I decided I should confront her. What is on her mind I really need to know. I decided to go at her place..
