Would you really stop PE if you knew you could gain 2 more inches after your goal ?
If your goal is 8 x6 and you reach it do you think you would stop at that point if you knew you could go on to 10 x 7? Yes, I realise that is going to be too big for quite a number of women,especially in length perhaps, but there are cock cushions that can be worn during sex in those cases, and with lube the girth will probably not be a problem often.
Do you view 8 x 6 as great , but 10 x 7 as awesome. Or do you view 10 x 7 as simply overdoing it and you wouldn’t consider it?
My mindset is that I would very much like to be 9 x 6 1/2 but I can’t be sure I wouldn’t want to move on to 10 x 7. I may never know anyway, because that seems quite a bit out of my range at this time.
