Hey there! It would seem to me that perhaps your girlfriend has been going elsewhere, or she does have toys that you don't know about. Being a female, I know that they only time I ever get looser is when I have been having sex regularly, or using a vibrator regularly. I don't know of any way that your girlfriend could just become looser, esspecially if you haven't had intercourse with her recently. I wouldn't go and accuse her of anything, though I would pay closer attention. Some things to think of, was she wetter tonight, is she close to menstrating, and you didn't say that you had sex with her, only that you stuck your fingers in her, could any of these be a reason?! Good luck *S*
