Why does This happen...?

i masterbate with a pillow but afterwards i get really bad yellow smelly discharge what should i do about it??by the way it only happens after i touch myselfWhy does This happen...?
Any discharge coming out of your vagina should not smell. I would go to your GYN and see if you have an infection of some sort.
Even if this is something that only happens when you masturbate. I would still get it checked out.
It won't happen if you go straight into the shower
Well, you could just stop doing it.
