Key points
1) I had a very brief relationship with my current girlfriends sister. The extent of it was kissing and it didn't last very long. Maybe a few weeks.
2) Current girlfriend used to be best friend's girlfriend of a year and a half. I've been with her now for almost 2 years. They were broken up for a year and a half before we started dating. Best friend is no longer a friend.
3) I love her to death and she would do anything for me, but I feel like I've had zero experience. I moved off to college 150 miles away. I don't want to leave her, but at the same time, I wonder if the relationship is hindering me. I know shes happy with me and would 'probably' even marry me eventually if things kept on the current path. I love her too and its almost unthinkable to break up with her. Yet I still have those thoughts and I still wonder if its right.
4) I cheated on my current girlfriend very early on in the relationship by getting drunk and making out with a girl I met. I stopped it before sex happened, and told my girlfriend about it the next day. We've moved on from this.
Am I normal to only have this relationship at 24? Should I explore other women?
If you really love this girl, you need to make a better commitment to her, you're very lucky she gave you a second chance. Try to be with her more, as this will show how much she means to you. Even the occasional "drop-in" can reassure her of your love.
Wishing you the best.
I didn't settle down until I was 31 years old.
Would I change a thing, what do you think?
