Everyone has encountered it at least once. I suddenly tried living with a mentally unstable girl for 3 days and 2 nights! Is it because she wants attention, even though she may seem strange at first glance? She always wants to be connected to someone. That's why she's very positive about sex. We went with the flow and had sex right away, in bed and in the bath, and became lovey-dovey in just 3 days? Mentally unstable girls are actually cute and sexy.
