Anyone else have an itchy anus?

Gabriela • First time mom. 23. Due 06.26.17
The doctor had said I had mollusum collusum which causes itchiness, but last time he checked back there and said I didn't have any. 
The itching usually happens after going to the bathroom but I always clean myself well.
What else might this be? Does this affect the baby?  Kind of embarrassed to ask doc about this again. 
Thanks!
