Im asking this for my girlfriend who, when we have sex, has a kind of thick white discharge that doesn't smell bad, but has only recently been appearing. I don't know what it is or if its bad or what to do. I was looking for an explanation.

To me you are describing a yeast infection. When you have sex and you withdraw your penis is your penis covered with the white that you mentioned??

Here is a list of types of discharge women can have ans what they normally mean:-
White: Thick, white discharge is common at the beginning and end of your cycle. Normal white discharge is not accompanied by itching. If itching is present, thick white discharge can indicate a yeast infection.

Clear and stretchy: This is "fertile" mucous and means you are ovulating.

Clear and watery: This occurs at different times of your cycle and can be particularly heavy after exercising.

Yellow or Green: May indicate an infection, especially if thick or clumpy like cottage cheese or has a foul odor.

Brown: May happen right after periods, and is just "cleaning out" your vagina. Old blood looks brown.

Spotting Blood/Brown Discharge: This may occur when you are ovulating/mid-cycle. Sometimes early in pregnancy you may have spotting or a brownish discharge at the time your period would normally come. If you have spotting at the time of your normal period rather than your usual amount of flow, and you have had sex without using birth control, you should check a pregnancy test.

Hello, that sounds normal to me. When my boyfriend and I have sex sometimes that happens. As long as your girl is not itching or burning and it doesn't smell she is just fine. And sometimes it is my boyfriend seaman that is on his penis.

If she feels different she should go see a gyno.

There's no pain or itching and its been happening for a week or two now, and its never happened in the past 6 months. Seeing a doctor is hard because she has no insurance.

There Are Women Clinics That Is Free. Not Sure Where You Live But They Should Have Them Every Where. I Didn't Have Insurance As Well And I Have Gone To One For My Paps And They Take Better Care Of Me Then When I Had Ins. You Can Google It And Find One Near You/ Her.
