Absolutely nothing wrong with being an unmarried 21yo. Why rush into marriage just because everyone is pushing it and then end up divorced 2yrs later? Wait for the right man, it'll happen. My DH and I were married after knowing each other only 3months. We've lasted 37yrs but there were some rough patches. Enjoy your youth! There will be precious little time when the babies start arriving...just ask my 30something niece who has a 3&1/2yo and a 6mo old. She's lucky to get a shower in the morning before going off to work!
