You may have Cystitis which is often called the " Honeymoon Disease" it is caused by bateria entering the Urinary Tract however that is usually accompanied by the urge to urinate and burning pain during urinating,lf this is what it is both you and your husband need to be treated a the same time otherwise it will pass back and forth all the time,however in the the absence of those other symptoms the itching and tingling you and your husband are experiencing may be caused by friction or slight bruising due to more regular and vigourous sexual intercouse than normal and will settle with time......
Speak to your Doctor about it and in the meantime drink lots of water or Cranberry Juice to flush out bacteria that may be lurking around and make urinating less painful should that start to happen.
I hope you both feel better soon

You all might have yeast or something. You should both be seen by your doctors.
