I am having a problem for some months, and I wanted to go to a doctor, but I was scarred. My problem is when I masturbate, and I sit on my back, when I sit in bed, sometimes, my right testicul, is going "in", and with "in", I mean, that the testicul is going inside. My right testicul, is a smaller then the left one. Is this a problem ? What can I do ? Only when I masturbate 2nd time, if I don't masturbate 2 weeks, and I masturbate myself the 1st time, no prob, but if I do it twice a day, my testicul wents inside a little bit. Please help!
