Is it normal how my penis is

Yeah, it's normal. It doesn't need to open unless something's going to come out of it, and if it stayed open all the time you'd probably be more likely to get an infection or something.

As long as you can stick it in a pussy. Your normal love.

Yes, it is normal. Think of the uncircumcised penis like that of a turtle in its shell. The head has to come out some time from within the shell.

Much better to be uncircumcised. When the head is out the sensation is higher during sex. So they say in the books.I don't know because I'm uncircumcised than never tried the other way. Personally a uncircumcised penis its aesthetically much better looking.
Many young guys boys not circumcised have trouble pulling the foreskin down. It hurts them when they start getting a hard one and it turns difficult to keep it properly clean.
Parents, most especially the father must teach his son how to make the correct "exercise" slowly to make the foreskin stretch as much as possible until does not hurt anymore. Therefore more pleasure having sex and have it nice and clean.
If the father his not a open minded person and teaches his son everything related to sex it might be complicated for the boy. Is father's duty to help a boy to discovered his own body and teach him to start getting pleasure from it since very young, as soon as the boy starts his first erections. Good for the mind and spirit as well as to have a balanced son without any shadows about what sex is.
I had a son very young when I was only 20, so I was a very young father. I tough him everything he needed to know.
