Had Laparoscopic Surgery, Severe Endometriosis, Not Able To Conceive.

Me and my husband have been married about 13 years now. We have never been able to have children, I have had laprascopic surgery and have severe endometriosis . Neither of us have ever had any std s that I am aware of, I got checked at the health department several months back. For the first time ever my husband currently has a cold sore which makes me extremely nervous and for the past several months he has had trouble peeing, off and on. I have bought lots of cranberry juice and it seems to help temporarily, he will be fine for a couple months, but then the trouble peeing comes back. Sais he feels like he has to pee all the time but can t. Could this be symptoms of an std or just something like a urinary tract or kidney infections? Hard to get him to a doc, anything I can do at home to help? I have no firewall on my computer so I will not enter my bank info on here... too risky. thanks anyway
