Help, Is it ok to play video games with the opposite sex?

My boyfriend loses his shit whenever I play video games with my son (he is 18), his friend who is 17 and this guy I met playing COD, who is 24. All gaming and conversations are open and never hidden from him, yet he is so mean and does not want me conversating or playing with the 24 year old, without any good reason. These guys crack me up so I do laugh a lot and they send memes in chat that make me laugh. My boyfriend got pissed, went on my name and told the 24 year old that he needed to stop. Then he deleted the messages. My gaming friend was so confused and thought he offended me. I only knew it happened because the friend wanted to know why I was upset. I was shocked. Why would my boyfriend feel the need to go on act as me and be rude?
My boyfriend played games with all of us, he was always included. I have never private messaged anyone, hid anything, or kept anyone a secret. I have not lied or did anything wrong. All I do is play games a couple hours a week. I have tried talking to him and it doesn't help. The guys I play with don't understand his problem either, especially since he can read and hear what happens during our conversations while gaming. A little back story, my boyfriend lied to me about several girls including a girl he played games with. He hid a lot from me, including about his ex. Is this why he is acting this way or does he have a legit reason for his behavior? I am literally not "allowed" to have any friends or conversations with anyone of the opposite sex without him being an ass to me and causing so many issues that I either give in to his demands or argue with him. Matter of fact, he is sitting across from me right now drilling me about what I am doing and who I am messaging.
