On one of my first trips, a few years ago, this entity was jumping into my body and I was thinking it was having sex with me. I was aroused and felt a warm energy around my penis without anybody touching it, when I started masturbating, the entity was like WTF are you doing? But kept on doing what it did... and i did also...
It was very intense, I had a window open, I was not in this world but i think the whole neighborhood could hear me screaming, it was a hot summer day with everybody sitting outside.
I never had sex with a real person on DMT.
