friends.....sometimes i get awake at around 3-4am in the morning and am afraid as most of the time i have discovered my DH's private part is erect and strong. Am really surprised and afraid....as it stays for long time. After that he leaves for office. If i ask him he says my leg just got touch to his penis. Whereas i know its not. I am clueless. Is it normal to get such erections daily at such hours when we sleep at around 10-11pm? Or should i get it as something else?
