Being male and older, it happened I have met women with sexual hangups, and I also talked about this deeply.
I have personal knowledge about traumas and how they affect the mind, on myself too.
It is way more common than you think, depending on where you live and kind of education you receive.
Don't feel "wrong", it is not you. It happens to many women, it's other people's fault, repressing sexuality, not your fault in any way! Guaranteed.
I am really fed up of reading people whose lives have been ruined to the point they cannot even have sex. You know, I knew a woman who was even scared of washing her vagina because of fear of touching her intimate zones. Is that life or emotional death? Is that fair? It is due to centuries of repression of sex, but mainly of WOMEN. Look at islam : it is the same of christianity, some centuries ago. Women were treated worst than dogs, with no rights. Imagine what a woman's mind may think about her own sexuality and intimacy. It is horrible and, even if I am male, I fully and eagerly support the respect of women and their nature, now more than ever. I left my family and cut them off my life as they are stupid abusive woman-repressers and exploiters.
The consequence of this heavy repression, programming and violence, through previous lives and mass mind power, it is exactly what you find in your mind right now.
I am truly and deeply sorry for you. Being 20 and not able to enjoy life at the fullest. You are in the age of joy!
You will find joy, soon, and I express my deep empathy for your suffering.
As many others said, really move out of there!
If you ask guidance to your Guardian Daemon to find a good place, you will find it. There's plenty of jobs for people who want to "move hands".
Your reactions to sexuality, are linked to some traumas your mind received. The first trauma is being educated by a family like yours, who only instilled in their childrens' minds fear, resentment, and sense of being unworthy and of no value, plus hate for own body and self. All of this leads to severe hang-ups that are stored into the subconscious mind. While the conscious mind wants to have a god sex, the unconscious (programmed and traumatized) wants to avoid that, so a clash occurs with mind confusion.
Apart of deep meditations like Munka, emotional body healing by HPs Lydia, detaching unwanted people (family) from your chakras, that are paramount and needed, you will need to reprogram your mind.
The Demons may guide you through life experiences that may recall your traumas or confront your programming, by positive situations. They did with me, extensively, and I understtood how it works and its benefits. The Demons are extremely smart in this, ask for guidance!
Oh, the key to success here is : loving yourself and your body.
Sexual repression leads to self-hate, because they teach you to hate a part of you : sexual organs and sexuality. It is part of human nature so, when they tell you it is "wrong", 100% you will end up hating yourself for even having a sexual desire. Because all people have sexual desires : it is normal and natural. So, it leads to self hate.
Don't hate yourself. I am sure you are a wonderful being, for the sole reason you chose to write on this Spiritual Forum and you are for sure Dedicated to the True God!
This means, being of high value. Love yourself and your sexuality, and the world of joy will open up in front of your eyes.
Don't be silent, don't repress your sorrow, vent out on here. Talk. You will be listened and feel better.
Seriously, take care.
