On the whole I'm too thick for a decent bj but that doesn't mean I don't like a partner to try and do her best, use her hands and develop her own technique.
My first wife struggled with all aspects of my size, once we were married and I'd given her kids she pretty much turned off the tap for sex and even oral.
I've always been involved in the lifestyle community which she never got her head around so I wasn't exactly starved, but with her withdrawing from all sexual activity I ended up just having other regular hookups with women who were more enthusiastic, the marriage obviously turned sour so I binned her off.
She was in it for my money, a proper gold digger but couldn't handle the dick and wasn't interested in trying anymore.
I was young and nieve thinking it'd work but it didn't, if they can't handle the dick or just not interested it's best to quit bro and find some who can, there's plenty out there.
