Is it normal for my boyf to rub his finger on his anus then enjoy smelling it?
Every night for the past week or two when me and my boyfriend get into bed he'll put his hand down his pants and rub his finger along his anus. After doing so he then puts his hand close to his face and sniffs his fingers, he says he enjoys the smell of the 'sweat' from his arsehole/arsecrack. Is this normal??
