It sounds like you might watch some more videos, so I would recommend this site: (I have nothing to do with it)
http://www.pornoamateurs.be/
It is mostly amateur male-female sex, with not so great camera work sometimes. But there are some good videos there where the participants are into each other in a way that porn stars can't quite reproduce.
There are plenty of other good sites out there to find whatever videos you want. So have fun searching.
