Sex is too serious a matter to be left entirely to your genitals
The consequences can be quite serious, unless you think about your goals and priorities, what your're willing to do, and not willing to do.
Lots of people aren't doing what they know they should because they are uncomfortable talking about their decisions.
They're to embarrassed to bring up the subject.
They fear rejection.
They just aren't sure how to say what they want to say.
It's a lot easier to have sex than to talk about it, but talking and planning ahead can make sex much better.
Remember, you should only have sex when you want to, only with those you want to be sexual with, and only in ways that are enjoyable and as safe as possible.
