I blew my load in my girlfriends hair and didn't tell her about it on her lunch break
Did she have a problem with it?
No, but I let her go back to work like that.
That could be really embarrassing. You should have told her the truth that way she had the chance to clean herself up.
She looked cute when she walked in with my load in her hair.
You disgust me.  She has to deal with other people who could make fun of her. Nobody thinks a load in hair looks cute.
