I’ve noticed recently that after I shower and I look at my ~downstairs~ that when I part the “flaps” that there’s a tiny amount of white substance on each side in ~crevices~ that i’ve cleaned out with a cotton tip. The cotton tip is slightly yellow after but I’ve been tested for STIs since I last had sex. Is this just discharge? I have no itchiness or irritation though, it’s just there? Should I be cleaning more thoroughly down there? Just with water right?
