Just to be clear I was talking about my testominal in that post and for many men the psychologial aspects or the ...... of distractions like heavy masturbation is the case.
I understand your issue is quite physical and I hope that you will be able to recover or find new ways to deal with soon. Anyways, opening up the sexual relationship you have with your wife will be risky even in the presence of a understanding and friendly man. So, my opinion is that you might have to be careful. Chew your trials bit to a bit, perhaps you might take some pictures with your wife and try some exhibitionism first. See how you both feel with other men dirty talking over her body, for example.
