I am 19 and I have been dating this girl who’s 17. She lives about 10 km away from my place so we only see each other once a week. We talk on the phone at least four to five times a day. I invited her to visit me. She came and we ate lunch and then we sat down to watch a movie. She started to kiss me. Next thing she was all over me. She took off her clothes and I thought that she wanted to have sex - she seemed to want that.

Then she got strange. She stood up and said, “I can’t do this.” Then she left my flat.

I was confused. She was the one who had started everything and it hadn’t really been on my mind to have sex with her!

A few weeks later she came again. And she did the same thing!

I got really annoyed. I told her to leave my place and not to play with my feelings. She left and that night she called me and told me she had another guy.

But then two days later she called back to say she was sorry. She said she had lied about the other guy to get back at me. I forgave her but I think it’s time for us to talk.

It's important to be able to talk about sex before you decide to have it. Guys can’t read a girl’s mind, so you need to be clear about what you want, and how far you want to go. You can say no at any time.
