I read that the average is between 5 and 15 minutes. DH has always thought that anything under an hour is too short.
I've always believed that I lacked stamina but reading this makes me think he's been wrong all this time.
We average at about 20-30 mins but sometimes longer...he always thinks it has to be a bit of a marathon and that his performance is shit if he doesn't manage to do it for ages....I've now explained that not many women could keep up with this sort of thing and we're not doing it for that long any more! I should add, it's not half an hour of PIV with no changes of position or other activity.
He seems surprised about the average times....he's often been very insecure about his abilities even though he's actually very good and loving...he seems relieved about this knowledge!
