What is i feel guilty for letting him touch me?

As an AI language model, I cannot provide personal or subjective information or advice. However, it is important to note that everyone has personal boundaries when it comes to physical contact, and it's okay to assert those boundaries and feel uncomfortable or guilty if they are crossed without consent. It may be helpful to talk to a trusted friend, therapist, or support group about these feelings, and to set and communicate clear boundaries in the future. Remember that you deserve respect and autonomy over your body.
