My wife was 18 and I was 20 when we got married so I think I can speak from experience.
The notion that you cannot experience life after marriage is one I will never understand. Hopefully you got married to spend the rest of your life with each other, that is what marriage is, whatever your reason, though it is best for love.
In your marriage you two will experience life together. You've got someone significant to share the high points and fun with, to laugh with and celebrate accomplishments and the good times. You also have someone to help you weather the rough times, failures, and tough situations. You can lean on each other and comfort each other. To me this is all much better than going it alone.
There are still things I do on my own as they are interests my wife does not share, however I know she is proud of me in my success in my hobbies as well as my abilities, and I get gratification from this.
We have things we enjoy doing together like going to car cruises and car shows, movies, and dinner. This is bonding time.
We've taken our kids to caverns and caves, on a houseboat for a long weekend, and many other weekend excursions. Just the two of us, we've been to Myrtle Beach (we live in Ohio), country bars to listen to local bands (neither of us are even drinkers), and to movies with friends. We were on a couples bowling league. We've been to a number of plays including seeing Phantom of the Opera 3 times, once in Canada.
I have pursued my hobby of making replica movie props the same way the originals were made for the movies. Ok, maybe a little geeky, but it illustrates that I still do thing things that interest me and I get to "experience life."
Who said you have to go out, party, get drunk and pass out so that people you thought were your friends can draw on your face in marker and post the video on youtube while you puke your guts out and feel like crap the next day? This is "experiencing life?" Being stupid is not a requirement of experiencing life, nor does it improve how others see you. The repercussions aren't much fun either.
So I hope from this you can see the positives you have going for you and that you are not missing out on the irresponsible partying and negative consequences that you don't need to deal with. Instead, have fun doing "real" enjoyable things that don't have negatives to be dealt with. The less time you spend dealing with negatives the more time there is in your life for positives. ;)
