DH and I have been together for 9 years, married for 5. We're early to mid 30s. We have sex fairly regularly (2 or 3 times a week depending on where I am in my cycle).
He has never, ever had any trouble getting it up or keeping it up.
Is that unusual? Is it something that will change as we get older perhaps?
Reading this forum and speaking to friends it seems he's fairly unusual.
