Guilty orgasm

Whenever i have an orgasm wether it be while having sex or masturbating i always feel extremely guilty after like i did something wrong or bad .. idk why . My mom never shamed me or said things that would make me think its bad & my family is not religious so that wouldnt be a factor .. no one in my family even talked about orgasms specially so i dont know how negative feelings got associated with orgasms but its been like that for as long as i could remember since the first time i ever masturbated ..
