The first time I went out to live with a girl, I didn't know what it meant, so I opened a double bed or a big bed.

The first time I go out to live with a girl, whether to open a double bed or a big bed depends on the relationship between your and the wishes of both parties.

1. If your relationship is average or you have no clear intention of each other, it is recommended to choose a double bed. This can avoid some possible embarrassment and misunderstanding, and at the same time respect each other's privacy and space needs.

2. If you are close or have a clear intention, you can choose to open a big bed. This will make it easier for you to communicate and interact with each other, and at the same time, it will better promote your feelings.

Generally speaking, this decision should be based on your's relations and the wishes of both sides. No matter what kind of room you choose in the end, you should respect each other's wishes and feelings and keep an appropriate distance and respect.
