New to the site - great forums I guess from reading the forums that a big penis is considered a good thing(?). I am above average but by no means huge - I really enjoy sex but I have the constant concern for my girlfriend that I am going to hurt her (esp. in the deep penetration positions such a 'doggy'). Usually I have to hold back to avoid hearing screams of pain rather than pleasure. Any suggestions re positions to allow me to bang away happily without the fear of a post-sex beating?
