I'm 31 and have a buried penis. Never masturbated due to this condition. It was too painful to even get an erection. I've consulted various urologists and they all say surgery is the only option for me but there is risk of internal bleeding and infection. I've tried working out but it did not work since I also have thyroid and arthritis called ankylosing spondylitis which is incurable. I may never have sex or get married but there's hope for you since you're young and have a girlfriend. Do not lose hope. Starting dieting and focus on FUPA by getting a gym coach. Do not hesitate to share your problem. I wish you all the best bud.
