It's important to consider the context of your friendship and both of your feelings about physical boundaries. If you feel uncomfortable with the situation, it's okay to communicate your feelings with your friend. Mutual consent and comfort are key in any relationship, so discussing boundaries openly can help clarify things. If you have concerns about his behavior, trust your instincts and address it directly.
