I understand that it may be. Just as erectile dysfunction is a fairly common complication for men.
But there are a lot of other possible reasons too, and all of them are worth discussing with your doctor. I know that, for me, tiredness, blood glucose and stress are hugely influential.
The problem is that this is such a taboo subject, isn't it?
Good on you for posting on it! I hope the thread stays current and more people post, because the more it is discussed, the easier it will be to discuss. If that makes sense.
