I have always thought that my body - its height and weight - is quite unusual, not in a good sense though.
My measures are: height = 182 cm (5,97 feet or 71,65 inches), weight = 58 kg (127,87 pounds)
I am a male, 36 years old, European origin.
My weight has not changed over the years much.
So my question to vote on is: Is it normal to have this weight for a man?
PS - In your comments I would appreciate if you could mention whether you have ever heard of something like my case. And if you are a girl / woman, whether you could imagine having a long-term relationship with a guy with my measures. (In general, not with me, to my surprise I am in a long term relationship with a woman who says that my measures are OK for her, so I know it is possible to have a great relationship also for a guy with such a funny body but I am interested in other people“s attitudes).

I think it is absolutely fine. However you look, stay healthy and positive, and everyone would like you. On top of that, it's always the personality that counts in a long term relationship. A perfect-looking guy, but a horrible attitude would never win my heart!
If you feel good and you don't get sick often, don't worry about it. If you're having health problems or you're concerned about your health, ask a doctor if you need to gain weight.
