Hi. So, a large amount of white discharge is happening? Does it itch? Or is there a smell? If it itches, that is a good indication along with thick white discharge that you have a yeast infection. The fact that it is white is actually a good sign that it is healthy. But because it is a change for you, perhaps you should talk to your doctor about it. They can swab it and quickly tell you if it is just regular old discharge or an issue. Also, our hormones can shift and cause changes in our discharge. So, this may just be normal. But get checked in case it is not.
Possibly you and he should both be checked at the doctor.
