Why he won't kiss but will do other things?

He might avoid kissing due to personal boundaries, past experiences, or a desire to take things slow in the relationship. Kissing can be an intimate act that carries emotional weight, and he may not feel ready for that level of closeness yet. However, he might still enjoy other forms of affection or intimacy that feel less vulnerable or more comfortable for him at this stage. Ultimately, it reflects his unique comfort levels and relationship dynamics.
