wtf is it

What are those clumped white odorless substances found normally after sex. (Idk if its during or after bec i Noticed it after i had protected sex). My boyfriend and I had sex yesterday and i noticed the white odorless thick clumped substance on the bed and near my anus. The condom never broke so what is it? 
Is it from the lube of the condom? Is it my cum? Is it his cum? Is it a vaginal discharge?
