Cuca area

Okay so I was finally able to get comfortable enough for my boyfriend to see view me down there light on and all so I've been staying extra clean down there (shaving ) .... So I was wondering how I could get rid of my "dark" areas after shaving ... You know how our armpits still have dark areas well I have the same issue down there and I have some on the edges of my vag leading the my thighs .... Anyways so please ladies any tips or does anyone have the same issue ? I had brought this up to my friends and they thought it was silly or they were to embarrassed to relate and I didn't want them thinking I had a hygiene problem because I'm super clean and I thought these dark areas were normal
