Tissue like discharge

I have never seen this before and its freaking me out now. I have seen it 3 times right after my SO and I have intercourse. The best way to describe it is as a White Wet looking tissue paper. No odor, not sticky and not itchy after. I went to the Doc when I saw it the first time and got a pep smear done. Everything came out fine. They did say i had a lot of discharge but that it was normal. No meds given.

I have seen it 2 times after that. Has anyone else experienced that..? What is it..?
