I know exactly what you mean. My bf has never been interested in BDSM, so I started... experimenting with a wonderful and understanding Dom from this site. The first time we played together, it just felt so right and I knew this was what I was missing. Last night, I asked him if he would please consider being my online Master, and he said yes! I think I fell asleep smiling... I'm smiling again just thinking about it...
As for what exactly makes if better, I don't know if I can put it into words. It's just fulfilling the reasons I'm a sub. And it's great.
