Hey, thank you so much for this thread! Your comments seem pretty genuine and the positive response you are getting from your wife is pretty hot. It has inspired me to start PEing !
I am also in an interracial relationship (with an asian woman though) and my starting stats are pretty similar to yours: BPEL 7.5" , EG 4.9" . I have a fetish about mine being the biggest dong my tiny asian has ever had, but I think I will have to make some gains before that's the case (especially girth). More importantly, I want to have harder and more consistent erections, because those rare occasions when it's rock-hard is when she's the most randy and loud. Of course harder woods just feel better too. Many years back I started watching way too much porn and it's desensitized me - since then I haven't been able to consistently have those sort of erections. Also, since we stopped using condoms my staying-power has dropped by something like 60% and the reduced friction means less pleasure for her.
Nonetheless, I hope to be her big-donged porn star/ sex god

. Your thread has convinced me that this is possible!
If my gf's response is half of what you said your wife's has been, I would be delighted
