In the last couple of years, I started to loss the ability to reach a full erection, sometimes I do it, sometimes not.
It started to take too much time to get a full erection (20 minutes or more, when it happens). But lately I only reach half the length, even though its enough erect to penetrate, it isnt the same lenght.
Another difference is that without full erection I lost it in seconds whereas with full I take more than 10 minutes and I am not so sensible by the refractory period.
Its only my appreciation? Or it could be a vascular problem? or its normal by the age of 35?
