My little sister never stops masturbating. i havent been sleeping well lately because her room is across the hall from mine and i can hear her moans. it kind of sickens me that she is only 12 and she masturbates all night. i havent said anything to her about because she needs her space and she might just die if she that i knew what she was doing. its distubing and she does it until she falls asleep.(which is around 11 at night) so i only get abot 6 and a half hours of sleep because i have to wake up at 5:30 for college. is this normal???
