So, this is gonna seem odd to say, but my boyfriend and I noticed something weird. Can anyone help? When I guess you could say masterbating, we could feel the little tube thing on the inside normally. Now, however, we can't feel it anymore, it feels like it vanished or sucked in or shifted somewhere else. I find it to be strange, but I also thought maybe it's cuz it was right before my period started, but we noticed it about....five days before my period. Should I be worried?
