Sexual aversion disorder (SAD) is a type of sexual dysfunction in which a person has a strong dislike for sexual stimulation. The avoidance could be to a specific aspect of a sexual encounter, such as penetration, or to more general actions, such as kissing or touching. Sexual aversion is a possible cause of anxiety or panic. Aversion can be caused by a history of trauma, untreated sex pain, medical conditions, or a subtle (or overt) sense of coercion or pressure around sex, but there isn't always a clear cause.
