The problem with popping picture like those you never know whether or not the person is doing it right.

I am going to say you probably have a male and do not pop him properly (could be wrong but that would be my guess)

Usually mistakes are the other way around you buy a female and it's a male.

If you are new to this I assume you are new to popping too therefore you might not be positioning your fingers properly and might not apply enough pressure.

The best is to have your BP double checked by someone experienced in popping.
