Nope
Actually, a new study from University of Michigan has shown that overweight boys may, indeed, have delayed puberty:

Some boys can start very late, into their late teens. However, if you are concerned, speak to your doctor about possible hormone issues.
through puberty
it is normal
Reasons for not going through puberty (for a boy) would include damage to the testes as the result of an illness or an accident or the removal of the testes (castration).
No not at all. Some people are late.
hi mate
If you have not reached puberty at 18 you need help from a doctor to start it with medical help.
A boy with one testicle goes through puberty the same time a person with two does. The second testicle is a spare!!!! You only need one!
The average age at which most boys start puberty is 12 or 13 years of age. But puberty is very variable and the is a wide difference from one boy to another so the normal range for boys to start puberty is anything from 9 years old to the late teens.
When a boy begins puberty, his voice will lower. There is no significant difference or change in voice for girls.
Yes, it is very much possible. But people going through puberty should not be having sex. Be sure to use protection in future.
17 sounds a bit late to have not even started. I'd contact a doctor and see if there's any hormone problems.
