Hi Doctor, Dis is sandy, male, 25 years old. I started masturbating when I was 16 and been doing till today. I enjoy doing that several times even in a day. Sometimes I go mad and do 4 to 5 times a day. It will be quite good dat day and later also. But when it comes to do sex with a woman its not being erect for so long. Firstly my lower skin attachment below the penis without condom does?t allow me to insert into a tight vagina and secondly it does?t stand hard not more than a minute if I do with condom. Unable to satisfy my love on bed. Kindly advice me with the tips and solution for my better sexual life. Waiting for your revert. Thanks.
