My husband would HATE to be put in that situation. I know this so I would never have him go. Some men like to socialize but many don't. Actually, my BIL is like this too. Hates to go to these social events where you don't know anyone.
Because he did not know anyone there, he felt uncomfortable. Most men don't care to make new friends either.
Be careful about the grass being greener thing. Super social men can be annoying as they are always trying to hang out with others and possibly trying to one up and impress others. They kind of leave you hanging. My friend left her boyfriend because everytime they were at an event he would be off talking to everyone. She wanted to hang out with him.
