Retarded ejaculation can be good but other times it's a bit like the guest that comes to stay over for a few days and is still there after 3 months .....enough!
It's probably even exacerbated when the guy is fit and can just keep going and going and this is my problem and whilst the first 45 minutes might be pleasurable for the woman, the next 30 minutes start to get her a littel 'weary".
But, unfortunately, no easy solution.
