Satan is raping my mind

whenever I close my eyes , all i see is satans geniTalia. I’ve been experiencing this 24/7/365 for the past 8 years. I’ve kept it to myself. is this an uncommon experience? why am I experiencing this? I rather die than have a nonstop sexual relationship with Satan. Im actually an asexual woman who values innocence. I do not like my mind having a singular devotion to satan sexually, i want my mind to be in obedience to Christ. I can’t even think a thought other than satans genitalia. for instance I want to imagine the color green and instead of green I see satans genitalia. this is beyond unfair. I don’t know what to do.
