According to me you are not suffering from male pattern baldness. It is a mature hairline as you have long thick shiny hairs and you keep it one-sided. I would suggest you to not keep your head too heavy. And, also watch your hairline periodically because receding hairline can be inherited from family, but don't be too much obsessed with it. Worrying too much and tension can also lead to hair loss. And, even if you feel the hairline is receding after periodical check, you can go later for hair transplant for men . Hair Loss in men is common. And, there are ways to treat it. So, keep your confidence in the way you look now and later.
