Sex isn't just exciting and fun, it's important. It plays a big role in cementing our relationships. So whether you're starting out with someone new or you've been together a while, having a think about what you want for yourself is a good first step to finding the words that you'll need.
Some questions you could think about:
Blurting out your first thoughts can sound clumsy or overly negative. Giving yourself time to think will help you work out what you want, and give you confidence you know what you want to say.
You could give the other person a chance to think too. Let them know roughly what you'd like to talk about and try to find a time when you can both talk without being interrupted, maybe a long car journey or a walk in the country?
