The best piece of sex advice I can give is: don't be afraid to ask for what you want. No matter if you are vanilla or super kinky, with someone who is a one night stand or married for 20 years, your partner won't know what you want if you don't tell them. There's nothing to be ashamed of, and they will appreciate being able to make you happy. If it's just ‘touch me like this,’ you can say that in the heat of the moment. But, if it's something bigger like, ‘I want you to tie me up,’ my suggestion is to bring it up before you get in the bedroom. That way, you can talk about it at length without worrying about killing the mood. Just have an open and honest conversation with your partner. It might suck at first, and feel super uncomfortable, but it'll be worth it.
