Hello Jade and welcome.
Firstly I echo what Lyn says. To get the toolkit from the site (The toolkit is a set of booklets/leaflets which explain prostate cancer, emotions, sexuality etc) go to the Home page, then Information, then Our Publications. Well worth obtaining.
Secondly, no - you are not being selfish. Your reaction is perfectly normal as indeed is your husband's
He has had a terrible shock and on top of that he has been keeping that horrible secret clutched to his chest for three months.
He's in physical pain from other conditions too and is justifiably fed up with everything.
It is still very early days for him.
It's possible that he is shutting you out subconsciously. It maybe that his mind is telling him it will be better if he keeps his distance. He is afraid of his future, he may be afraid that he doesn't have one.
Do you have any indication at all what his treatment will be. Has he been able to tell you what his PSA/Gleason scores were.
Perhaps he feels that the closeness if sexual intercourse will weaken his resolve to keep you protected from how he feels so he rejects sex to avoid that situation.
From what you have said I have surmised that he appears to be in the cure camp.
Have you told him you are in this together. He might not know how this is eating away at YOU.
Our men are a strange bunch. Sometimes we have to get tough with them in order to get ourselves involved in their daily dealing with this cancer.
Like Lyn, I feel it's a lot to do with his other physical problems getting him down and this is just the icing on the cake.
Unless he can open up to you or his sons nothing will get resolved.
You, however, are not alone because you have found us.
We cannot drag his head out of the sand or give him a kick up the behind or any other kind of wake up call.
If you cannot persuade him to go and talk to his GP or you or his sons then you may have to grin and bear it for a while.
Be patient. Get the Toolkit and leave them hanging around so he sees them. If nothing else they may make him open up to you.
Best wishes, keep posting and we'll keep supporting
