Is it normal to jerk off with a friend when you have a boyfriend?

So for along time me and one of my buddies have jerked off together. Now I have a boyfriend and I'm wondering if its ok to jerk off with my friend (with out any physical contact, just watching each other and looking at porn).

Basically, is it considered cheating to masturbate with another person even if there is no contact? Would it be normal and/ok?
