No, if a guy goes down on you (referring to oral sex), it does not necessarily mean he loves you. Engaging in sexual activities, including oral sex, can occur for various reasons and does not always indicate a deep emotional connection or love.
People may engage in sexual activities for a variety of reasons, such as physical pleasure, curiosity, experimentation, attraction, or simply to satisfy their partner's desires. Love and sexual intimacy can be connected, but they are not mutually exclusive, and one does not guarantee the other.
It's important to remember that love involves more than just physical intimacy. It includes emotional connection, trust, communication, and a commitment to one another's well-being and happiness. Sexual activities can be a part of a loving relationship, but they don't define it entirely.
If you're uncertain about the nature of your relationship and want to understand the person's feelings better, it's crucial to have open and honest communication. Don't assume that sexual acts are equivalent to love or commitment. Talk to each other about your feelings and intentions to ensure that both partners are on the same page regarding the relationship's expectations and boundaries.
