My friend Larry gave me a copy of Shots photo magazine, I love it! The magazine is filled with wonderful, innovative and exciting photography (lots of portraiture). I subscribed to the mag and also got 10 back issues.
They have various ways to submit work including an online process. I will try to make a submission to their next call for work, portraits. I will probably submit a combination of sex worker and boxer photographs.
