Did the gyno say WHY her muscles were tighening up? There's been comments about that sort of thing in the past. There's a medical condition that is psychological in some aspects which causes the woman's vagina to contract so tightly that nothing can be inserted. Usually this is due to some trauma in the woman's past- it's a form of PTSD. How does your wife feel about all of this? Have you talked to her at all about her take on not having sex? Do you know the vaginal tightening is because of complications from pregnancy, or is it because of some deeper psychological issue? Have you been to another doctor to get a second opnion? Educating yourself and your wife and committing yourself to open, honest communication about her body and her situation is your best bet here. Good Luck
