Sorry to disgree with the consensus, but I think yes, in the longer term. People change as they grow up and I think I changed a lot between mid-teens and mid-20s. You are going to be a very different person in 10 years, whereas he won't have changed that much. So what attracts you now might not be there in 5 years.
And as others have said, when you're still in your early 20s, wanting clubbing, fun and excitement, he'll be in his 30s, and probably won't.
But even so I wouldn't disagree with the advice to 'go for it'. You've nothing to lose and lots to gain. Enjoy what you have now, don't not do it just because you're worried about the future.
