I (16, boy) have a girlfriend. We love each other very much and like it a lot when we cuddle and make out. We want to have more sex now. How do we do it right? How does the penis find the vagina?

It is normal that you are unsure.
You have not had sexual intercourse before.
The first time is not easy for many people.
When you have had sex more often, it gets easier.
You get to know each other’s bodies better all the time.
You need experience with each other.

When you caress one another, you get to know each other’s bodies.
You can touch the vagina and feel where it is.
You can carefully push a finger into the vagina.
Your girlfriend can caress your hard penis.
Your girlfriend can insert the penis into her vagina herself.
It helps to talk to one another while you are having sex.

The important thing is: Sex should be fun.
If your girlfriend says: It hurts.
Then you must stop.
You need time to get to know your feelings during sex.
After a while you can be like a good team.
