So me and my gf were fooling around, and I slipped a finger in, and then brought it up to her lips and put my finger in her mouth. She got all grossed out, and it has actually affected our relationship in the past few days (she's moody as it is). I've never had sex with this girl, but we've been naked together. I've done this one other time to my ex-gf and she didn't have any problem with it. What do you guys (and girls) think?
