Vaginal / Uterus Health :: Thick White Liquid Discharge And Pain?

I am 23 yrs old and i have this problem that i have a white discharge from my vagina.

sometimes the quantity is less and sometimes more and sometimes doesnt happen. sometime back i got white thick discharge which was watery but it got stretched. i was like a chewing gum which i could take out by pulling off my vagina. after it dried on panty, showed as light yellowish lump or so. it also came out after bowel movement or even pee.. the quantity got lesser on its own , then i had my xams and that time it again started but was not the type i told, it was just simple liquid which when dried got into flakes.

after that for sometime it almost stopped except for after orgasm.

currently its like usual discharge but in a lesser quantity only.( also i got more red lumps like small mass during my period flow)

i dont know and worried regarding this. is it normal?

ALSO The second thing is that when i get aroused the vagina gets wet but now it pains while getting wet naturally unlike before.
