Welcome to adulthood, it just goes downhill from here. I am going to break with the crowd here and admit that I don't frequent the TB board much. I've checked out a very few topics there but I don't think I've ever posted there. I think that's because I never considered myself a teen baby in the past. My first time wearing diapers was as an adult at 21 and even though I had dreams and fantasies about regressing before then I never once sought out information or tried to connect with others when I was a teen.
When I read the title, I thought this thread was going to have something to do with a near death experience or talk about something paranormal. I am glad I was wrong on all counts, LOL!
But yea, hate to burst your bubble but, 18 is still a teen. Yes you are considered 'of age' at 18. But I consider 18 and 19 to be teen-age years. I've posted in both adult and teen areas of this forum. Granted I tend to stay in the adult area more, but there have been a few times that a thread caught my attention and I commented on it.
You will love being an adult! There comes with it a few new challenges you may or may not have ever had before. But the rewards of being an adult are great!
