Wow, 15 years, very nice.

For me, it will be 10 years in two months. And I'm only 32, so I've been exclusive since 22 (and he is one year younger than me, so for him since 21). We are at the point where we finish each others thoughts constantly, have too many inside jokes that other people don't undestand, and can just give that look and know its time for sex!
