vulva ??

Ok so I always have " Vulva irritation " There's nothing wrong with me I've been to the doctors ( I'm a virgin btw ) it's not like a burning or itching feeling it's more so annoying. What helps is I put Vaseline on the outside of the vulva ( btw I have no problem with moisture down there ) and I normally apply pressure by changing the way I'm sitting or putting like a pillow or something in between my legs. It's really annoying and Idk what the problem is. I don't know when I started and it sucks. It may be from birth control withdrawal ( I was on the pill "Lo loestrin fe " for my cramps) I was forced to stop taking the pills because my mom stopped after maybe like 7 months I was suppose to go for a check up and then get my next set continuously if I liked the pill. I was fine with the pill. But anyways I always have this and sometimes really bad lower abdominal pains but I'm ok the doctors say that I'm fine. Idk what to do I wash with organic soap and I only use warm water on my Vag so like I'm confused. Any advice ?
