What is sex like the first time?
The first time you have sex is different for everyone.
You and your partner decide together what you want to do. You do not need to have sexual intercourse. If you do not feel ready, you do not have to do it. You can have sex in many different ways.
Try to relax. Taking your time can help.
Make sure nobody can disturb you. You will be more relaxed.
Make sure you are both aroused enough. Stimulate each other, for example by exploring each other’s body.
Talk to each other about what you like and what you do not like. If you are aroused enough during your first time, sex will not hurt for most people.
