Hello Mam/Sir, I am 23 years old and I just recently started masturbating by rubbing my vulva. I used to think it's ok to do that as I am not using a vibrator but then I do release cum every time when I rub that part. The problem is I do it daily and sometimes twice a day! Also, it isn't guilt free and affects my concentration when I study. I sleep more after masturbating and this is my peak time, I want to concentrate more on studies. Also, Is masturbating daily affects my eyesight or memory too? Please help me. I am a hypothyroid patient and takes 100 mcg from past 3 years.
