<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I have a masturbation technique where I lay down on the bed with my stomach and then place my penis into sheets with my hands and start rubbing my full body up and down. Shortly, I rub my penis into bed sheets. I can t masturbate with my hand because my hand is too rough and i get no effect, just my penis gets real hot and there is no pleasure. Now, I have 2 questions. First one the most important: Will I have problems ejaculating when I will be having sex with my girl? And the second question: Can I learn to masturbate with my hands like all my friends do because it s more normal and you can masturbate anywhere you want - you don t need a bed? I am just really worried that I will have sex with a girl and we will be sexing for half hour and I won t be able to ejaculate because I m used to bed rubbing...  <response>: Degree understand your concerns went through your details.
