Have you ever visited Iran?

I am planning to visit Iran for trip and to meet my old penpal friend. :))
She and I have been exchanging our language, and we have become good friends.
Currently, I am in Australia for work and to study English; my visa will expire in August.
I have saved some money, so, I have been considering what I will visit, or how I will spend this money .
I told my friend that I am planning a trip.
She told me to visit Iran, and I have decided to go there; but I have heard some bad things about Iran, and my friends are concerned that about me going to Iran.
I have never seen her in person, and and their culture, (my friend think i wont be able to hand shake with my penpal friend because in Iran, their culture is really strict for men) and there are several dangerous things around Iran like terrorist, such as ISIS, or honor killings. 
So, they succeeded in making me scared.
I trust my penpal friend; I bought a flight ticket, and I searched online for information about Iran. 
It was different from what my friends were concerned about.
What I discovered, is that Iranians are nice people and Iran is a powerful country,  more powerful than ISIS, and other dangerous countries cannot touch them.
So, I will visit Iran soon.
