Do you hangout with your significant other and their friend group?

I (F40) and my husband (M42) have been married 16 years. Occasionally my husband will host a game watch party (football) for his guy friends, sometimes I will make a dish upon his request but then I will make myself scarce. The gentlemen are pleasant but I have no desire to hangout with a group of men and my husband feels the same when it comes to my female get-togethers. However, we are learning this isn't the case for other couples, recently one of his friends started dating a girl who insists on coming, usually when this happens he will ask me to be present (I guess so they won't be the only female there) but its caused some of the other guys to feel uncomfortable or just not come altogether. The guys can get rowdy and talk vulgar during the game and don't want to censor themselves.

My husband spoke to his friend about this but he doesn't want to offend his girlfriend who actually enjoys watching sports. My husband suggested maybe he and his girlfriend watch the game together at their house (he said it in a nice way) but the friend says he wants to hang with just the guys, but his girlfriend would be upset if she's not included. How would you tell your SO you don't want them hanging out with you and your friends.?
