Dont stress, you are perfectly normal. I am 26 not married (bf for 5 years), no kiddos and just started my carreer. It is wonderful. I'm totally with you I don't think I will have kids until my mid to late 30's. I just want to travel and enjoy life, I worked hard to get where I am and I plan to reward myself a little before I have to share a checking account with someone and buy diapers!
I have a lot of friends that are young moms and they love it, and I get a little jellous because I'm afraid if I wait too long I wont get to be a MILF

but seriously, there is never a right time to do anything so do what you want!
Come on down to Corpus Christi, I'll buy you a drink.
