Ladies, how can I end the sex dreams about my ex?

Are you for real? You haven’t put yourself on the highest pedestal of your life. If you see yourself as the prize you would not even entertain the idea of going back.

You still have a sex drive? Mine is completely gone, men don't arouse me anymore.

Here is a visualization technique I recently posted as a reply to another similar-ish post:

I use this technique frequently whenever I find myself ruminating about past relationships/friendships/etc. or when I find I'm having these people appear in my dream life.

I've copy/pasted the relevant to you portion below:

"As far as still feeling emotionally connected to him, there's a visualization technique I use when I have to cut people out of my life (this works for scrotes/pick-mes/toxic family/friends/etc) but still feel emotionally/spiritually/cosmically connected to them that I find quite effective.

When you are in a calm, centered state, imagine the cosmic thread connecting you to them. Visualize yourself literally 'cutting the cord' (with a knife, scissors, or whatever cutting implement pops into your mind) and as the connection is severed, I like to imagine that thread instantly igniting, like a fuse, burning away that connection into oblivion.

Gentle heads-up though, in my experience, these toxic actors (male or female) WILL absolutely feel this broken connection (even if only on an unconscious level that they're too dim-witted to comprehend) and may even be so bold as to attempt to reconnect (phone calls/texts/DMs/in-person 'drop-ins'/etc) with you. When this happens, simply set/maintain/enforce your boundaries, block & delete (on EVERYTHING: phone/text/email/social media/etc) the person & perform the visualization again. (I've had some incredibly aggressive toxic individuals reattempt to connect more than 6 times. I simply did the visualization however many times it takes to get them gone!)"

In your situation, I would perform this visualization every night right before falling asleep until you notice that the dreams have stopped and you're no longer thinking about him at all when going to bed. Hope this helps.

Think about male depravity and you will never look at males the same way

seriously, though... this is a sign of complex trauma. you feel attracted to "trouble", to men who hurt you and mistreated you. it's not healthy. therapy might help, but reflecting upon your experiences and complex trauma helps even more. if i were in your shoes, i would do my research and work on getting rid of the sexual connection however possible.
