my penis is not growing

130mm penis - just over 5 inches is pretty well an average sized penis. You didn't say whether this is the size flaccid or erect?

It is said it is the amount of testosterone you have produced during your formative years that governs the size of external appendages as well as some genetic input...

At 17 your growth will have almost tapered off but there is little harm in hoping for another growth spurt as long as you don't pin your hopes on it...

Mother nature has equipped you and you can't take it back for a refund. There is no point worrying about what you can't change - far better to put your energies into learning how to use your sexual equipment well: that is your brain, your hands, your mouth and your penis (and sometimes a few other bits) in that order...

People, especially women, who place great importance on penis size are often ignorant, shallow and selfish and are best avoided. You will find as you age penis size will be less and less important - there is more things to do in life than have sex and a large penis can be a very real nuisance sometimes.

It is true many women feel the need to try a large penis but any increased excitement often comes from her seeing what she is going to be filled with rather than the filling...
I have met women who actively dislike being impaled on a large penis and say there is no fun or enjoyment...

I hope you have as much fun with your average-sized penis as I have had but never forget that with an average-sized penis you have to try a little bit harder in order to impress your sex partners.

There is no such thing as a small penis for most people, most of the time - only vaginas that are too big! A sensitive and caring partner who appreciates the benefits of an affectionate relationship will find ways to make the best of the penis you bring to the bedroom!

Pornography does a lot of harm to real sexual relationships because so many, especially the young, believe it is real. Let me tell you there are very few things to be learned from porn other than how to make titillating films for lots of money...

Your best chance of bedroom success and respect will be from learning to be gentle and caring of your partner's needs before your own.

I hesitate to say this because it isn't strictly ethical, but if you ever get the chance to give service to someone older I suggest you jump at it as it will be like taking a course at school...
