I am 30 years old single. Height is 170 cm. Weight 74 kg. Little bit obesity. My penis is very small and shrink. When erect maximum length is 8 cm. I do have a habit of masturbation by rubbing or stroking it on surface or bed. I don't enjoy hand masturbation like all other do. This might be because my penis head skin is tight & unable to move to & fro. Semen quality is like watery fluid. Delayed ejaculation. Low sexual desire. I feel ashamed of my small penis to maintain erection. I do masturbation weekly thrice by rubbing uncircumcised penis on bed. I don't get hard morning erection even after waking up like I do get earlier 5 years ago. I don't feel nightfall due to excessive masturbation. I get erection of very short duration now. Penis shaft length after erection is 3 inches maximum. I feel low confidence in speaking & poor concentration. I do have fatty liver stage-1 recently but not taking medication for that. Suggest me what to do before getting married. I know it is late. I don't take any medication now or earlier related to it. I am still virgin. I don't smoke. I don't drink. My growth of penis not developed properly from childhood.
