<human>: I'm going to see a movie and get food with one of my male friends/co-workers today, I told my bf I was just going to the movies with a friend. He just said to let him know how the movie is. It's 100% not a date, he's been in his relationship for 5+ years. I'm wondering if I should be telling him when its male friends vs female friends or if that just opens the door for more issues? 

We've been together for a little over a year and a half but have never specified male friend or female friends, usually its just names if we both know them or "my friends" if we don't. I've always been fine with him just saying "my friends" and I assume he feels the same. 

About a month and a half ago we broke up, we got back together around 2 weeks ago.

Last year I told him about a concert I wanted to go to but didn't want to go alone. I said one of my guy friends said he would go with me and my bf was fine with it "as long as there wasn't any funky business". That seemed to be okay. That was pretty much the only 1:1 outing I've had with a guy during our relationship.

Normally when I hang out with people its in groups so I'm not sure what I should say or if I just shouldn't say anything. Part of me wants to mention it to make sure hes okay with it, like out of respect. The other part of me doesn't want it to blow up and cause an issue. 

What is a normal protocol for this? We've talked about what we want for our relationship and its just us, no fooling around with other people, no dates, etc. It's exclusive.

<bot>: Should I tell my bf when I hang out with other guys (non-romantically) 1:1 or just tell him I'm hanging out with "a friend"?
