Can I get a virus with my iPhone?

I was watching a new video on youtube that the creator just posted. As I was finishing the video I decided to scroll through the comments. When scrolling, there was this one comment with a time stamp on a certain part of the video. Right below this, was a link to a random website. Instead of my thumb pressing the time stamp, I hit the link which directed to me to an adult website. I know that most adult websites and free movie sites tend to be malicious and computers would have a virus if not protected. But when I pressed the link, I immediately closed it after seeing the content as I didn't want any viruses. But my question is, is my phone now infected? Or am I safe?
