Her older sister had the same problem as me. Even when I'm with my girlfriend, I feel lonely...I'm in a rut and it's awkward...People who are similar are attracted to each other. ``Hey, you haven't had sex lately, have you?'' I was confused, but he kissed me forcefully... He pushed me down and we started having a relationship. I just wanted to fill the gap in her heart...That's what I felt like, but we also had sexual compatibility.
