Ok, so this may sound weird, but it's a fetish I have. Sometimes I enjoy gagging on cum

. Like, when I'm giving my boyfriend a blowjob, when he's about to cum I'll take his dick far into my mouth so when he cums it shoots in the back of my mouth/throat, which makes me gag and cough his cum up. I usually cough it up into my hands or something else and then eat it. I know it's weird, it just really gets me turned on sometimes, and he says he likes it too.
I don't know why I like it, I just do. I don't always do this obviously, only when I'm in the right mood, because if I don't really want to I might end up puking, and I don't want that lol.
Just wondering if I'm all alone on this one?
