I have, on occasion, used my boyfriend's toothbrush when I was desperate. It's gross, I know. But he's the one actually hounding me for MY moisturiser when he didn't have any. And it's really funny because he ends up having to use my shaving gel when he comes over to stay at mine - and his face smells like peach!!!

somehow I can put parts of his body in my mouth and not be grossed out. But the thought of sharing a toothbrush is disgusting!!!!
The thought of using something that goes in between the teeth to sweep out someone else's plaque and bacteria is soooo yucky!! Gah I'd rather kiss him that use his toothbrush! But I will use some of his lotion! haha

There have been a few occasions that we've had to share toothbrushes. One particular one was on vacation where my suitcase was lost for several days...but he had his.

He uses my moisturizer sometimes...I actually wish he'd use it more.
I steals my chapstick too...thank goodness he's not into eyeliner or lip gloss though
