So..Im 20 yrs old...and I feel like I'm just pathetic right now.?

First things, about the no protection thing, it happens, get some plan b and you'll be fine. You have 72 hours to take it, so you have time. There are a lot of people who have early on in a relationship and still have long enjoyable relationships. As long as you remember to bond emotionally and not get too caught up in the physical stuff, then you'll be fine. You are ually attracted to each other, which is really important, so you'll be fine.
