I want to know whether i will be able to control my ejacuation time and regain my sensation by leaving masturbation?? [/INST] Degree understand your concerns went through your details. Please do not leave your masturbation altogether. You should masturbate once or twice in a week. The numbness could be just because of continued friction. Ejaculation time can be controlled by diverting your thoughts to more serious things while having sex. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
