Knowing what you like in and out of bed is always good for your self-esteem, but we’re going to focus on between the sheets for this one. It can be difficult to feel confident in bed if you are unsure about what turns you on, so do some research! Treat yourself to some alone time and satisfy your curiosity – that means experimenting with toys, movies and whatever else takes your fancy. When you are more confident about what brings you pleasure, you’ll find that it’s a lot easier to be more assertive. That’s out of the bedroom too!
