Men hanging with friends

I see posts all the time about women complaining that their man hangs out with friends too much, leaving them at home with the kids.  Well my man is just the opposite. He STAYS right up under me and I don't think it's normal. When he has gone out, he back home in under two hours.  He's 25 and should go out with friends at least sometimes.....right?  I'm quite a bit older than him and I think it's important for him to do normal things. How can I get him to hang out at least once a month, without making him feel like I'm pushing him away?  
Addition:
Yeah maybe he is just a home body. No he doesn't really have hobbies, unless it's working out and playing basketball. I just think about this because of our huge age gap. I don't want him not doing things with his friends because he's worried what I might think about it. I don't want his family saying "see that's what happens when you love an old lady".  😕. Idk.
