Communication is key. It’s important to be honest with each other about your expectations and feelings throughout the relationship. If either of you ever feels uncomfortable or unfulfilled, it’s important to have an open conversation about it. Don't forget that this is still a friendship first and foremost – make time for activities you enjoy together outside of the benefits aspect of the relationship. This will help ensure that your connection is based on more than just physical intimacy. Respect each other’s boundaries at all times; if either one of you isn't comfortable with something, don't push them beyond their limits.
