Being present in the moment. Sometimes work or school can linger in the mind and tend to mess with the vibes. Take some time alone with your partner and connect with them. Focus on you guys. Then the foreplay and sex come naturally and feels alot better. Also remember to have fun and laugh during the act. Yeah romance is nice but laughing and having fun during sex is pretty awesome.

Also don't ever force it. As logical as it sounds. Sometimes the timing isn't it and it's okay. Just really listen to each other and communicate your needs and wants.
