Is my penis too big for women?

I have slept with about 6 girls and 4 of them dumped me because of my size. They said that it was too painful and not what they could handle. is there a fix for this? it is getting very annoying, everyone wants to brag about size but i got it and it is more pain then anything. the other 2 in more or less words said the samething as the others. Help???
