Is it normal to snowball with my boyfriend?

I am the kind of girl that likes to play with my boyfriends cum. I love everything about it. I love it on my face, my tits, my ass, inside me, but most of all in my mouth. One time after giving my boyfriend a blowjob, he came in my mouth, and I leaned up to kiss him like I always do after I swallow his yummyness. This time I hadn't swallowed yet and was still savoring the flavor. I totally didn't even realize it but when we started kissing I had a big mouthful of his cum. At first he was totally shocked and jumped back. "What the hell was that?" he yelled. "It was your cum silly boy." After I told him he suggested we try it next time, so we did, and he loves it. Everytime we have sex now it ends with us making out and sharing his load for like ten minutes. We each end up swallowing like half of it. I know this is probably pretty normal, but I wanted to post it with the hopes that it would turn you all on and inspire you to try the bonding experience of sharing your boyfriends delicious semen with him.
