There are certain milestones in relationships – staying at each other’s houses, meeting the parents and for this couple – the first fart. It took three years to finally reach the all-important milestone and to celebrate his girlfriend’s first pump in front of him, Ryan McErlean got her a cake to mark the occasion.

Ryan, 24, bought the cheesecake for girlfriend Kaylie Warren, 21, after she did a little accidental one while she was in bed next to him the week before. So easily done.

Below are 11 relationship milestones worth celebrating:

1. Giving Each Other Pet Names

If you and your S.O. have adopted cute pet names for each other, don’t be embarrassed! Embrace it as your own unique way of expressing affection for each other.

2. Meeting the Friends

Not everyone is going to get on fabulously right away, but meeting each other’s most trusted friends and starting to build those relationships is definitely a step in the right direction.

3. Talking About Your Exes

Being able to talk about the past, especially exes, demonstrates a strong level of trust and security in your relationship.

4. The First Time Traveling Together

Along the way, you’ll get to see and experience different sides of each other, and you’ll probably learn more about each other’s daily habits, quirks and pet peeves.
