Advice to me?

hiam naveen my age is 20.my family is a joint family living in tamilnadu.my Mom ia around 50 and wears saree low hip just below the navel when she is out and doesnt exposes much,some times if pallu leaves her navel get expose and it doesnt look vulger and it happens less often. But in home she wears a deep lowhip and exposes her navel completly and doesnt hide it at all even if anybody come to house. My question is whether ladies realize that the saree is stripped below her navel and whether they notices peoples watching it. also i want to know why they are exposing it.they are doing it purposley or not Another problem is on me My eyes get attention to her navel automaticaly and i feel some ual pressure I want to know whether this happens to all gents or its a psychological problem. if its the fact how can i change. I dont fell bad on my mom its her own way of dressing, if fault is on me and am doing wrong means advice me to change myself.
