I think if I had married her I wouldn't have been here now - I'd have been dead long ago.
We enjoy robust lovemaking daily, multiple times some days. I am a bit surprised to hear that you were not up to the task of satisfying your woman, as I always imagined you to be a stout and hardy bloke. As for me I am quite healthy and able-bodied, and years of vigorous lovemaking hasn't left me weak in the knees at all.
