Hi. I'm 18. I'm 160 cm tall and 55 kg weight. my left labia minora looks like it's swollen and it's blackish in color. It also bleeds and it's painful when i wear jeans. I'm a virgin and I used to masturbate using water pressure around 7-8 years ago. I no longer do such thing. And I'm not sure when does my labia start to swell because I never actually take a closer look at it. I just did so because it bleeds and I know that it's not my cycle yet. Can you tell me what to do?
