Am I slowing down my more extroverted boyfriend?

I know, it seems a bit silly to think, but sometimes I wonder if my boyfriend is not enjoying his company with me as I am nowhere near as extroverted as he is.

He is 27 and I am 23 and he is from a small town where everyone knows everyone, and I moved in with him about six months ago. My friends are over an hour away by car and train.

Anyway, he loves going out and will go out to all hours in the morning, sometimes till 5am. Most of these nights are guy night outs at the weekend where I am not invited to go. When we do go out together, he often tries to invite his friends out too. That would be fine except for the fact that he gets lost in a conversation with his friends and I get completely forgotten about and he will want to stay out with them if they offer somewhere else to go after.

We even went out to a party on our anniversary and stayed with disappeared with a stranger that he befriended and refused to go home with me after the pubs started shutting telling me: "I have made friends with someone here. Here are the keys and head up the road."

I do make effort with his friends when we go out and I speak to most of them with no issues at all. However, he seems to enjoy their company so much more than mine and would rather be out with them than come home with me.

I am just worried that he needs and wants someone who is more outgoing than me. Someone that wants to go out every weekend the same way he does.

Maybe I am being too harsh on myself as I am bubbly myself. Does anyone have a SO who is more extroverted than they are and how did they deal with it?

Note: I did not state, I have no issues with him going out with his friends because he is so sociable and I can't expect him to sit in the house all day.

Oh, another little update that makes me think that he would rather be single or with someone else:

Several times where he has been out to the early hours of the morning, he has told me that, on several occasions, random girls have come to the table and his friends are trying to hit on them and he will tell all these funny stories about the girls and what his friends and himself are getting up to. He does not seem to think there is anything wrong with having several girls hovering around them.
