Thanks for your feedback. It's definitely not toilet paper. It is more of a creamy mucus as Heather suggested. And I usually use unscented sensitive-skin baby wipes, not toilet paper. So, it doesn't make sense that it would be from that.
But, on the second topic, maybe I'll try the drying out theory and see if that helps with the cut. It could be moisture.
I re-read your first paragraph and it sound exactly like what I have experienced with toilet paper. I only use the Scott 1000' toilet paper, it doesn't leave any residue.
Hope that helps! =)
This might sound strange but maybe you should try using a different type of toilet paper. One that doesnt have scents or leave lint behind. Are you sure it's discharge and not from the toilet paper? I've experienced stuff like that when I use cheap toilet paper, it leaves a "linty" wet stuff behind. I think it might be from toilet paper.
Also on the sore, I get those once in a while, it's not always there but it looks like a cut that is red, almost looks like its bleeding and is in about in the same area you described. I've noticed that I get that when I do not dry off enough down there or if I am wet in that area for a long period of time after intercourse.
I think the "stuff" you're describing is creamy cervical mucus that just kind of sticks to your labia. I don't think you have an infection.
As for the cracked skin, I don't know what that is, but I wouldn't worry about it if your doctor says everything look's normal.
Hope that helps :-)
