I would consider stage one of the relationship would be the talking stage in this part of the relationship where yall see eachother every once in a while yall talk on the phone every night the only touching or skin to skin contact is maybe a hug the next level would be seeing each other everyday can't stand to be away from each other now once you get to about level 7 or 8 you can start the kissing or what ever after marriage is when you can start the extra curricular activities
