When it comes to approaching someone you are interested in having a sexual relationship with, it is important to remember that the most successful approach is one that is respectful and honest. It can be intimidating to approach someone about a sexual relationship, so start by being open and honest about your feelings and intentions. Make sure to communicate clearly what kind of relationship you are looking for and pay attention to their body language for cues as to how they may be feeling. If they seem uncomfortable or disinterested, respect their boundaries.
