Cuming during sex!

vaness

Okay so i can make myself cum from clitoral stimulation by itself or clit and fingering myself, but for some reason when my boyfriend and i are having sex and i’m rubbing my clit or he is rubbing it, it feels ah-maaaz-ing but i can’t tell if i’m cuming or not? like i think that i’m coming but i’m not sure and then i get annoyed.
