I Don't Understand...

I use Nair down there and keep it clean. I wash with water and sometimes Vagisil shower gel. I don't put anything down there unless it's a Summer's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> wipe or baby powder. But I still smell a fishy smell on my finger when I masturbate 😒. If this matters, my period is 25 days late but I'm a virgin.
