Voices are saying you gave that janitor a blow job, and he wanted to ejaculate on your neck.
I recall even in my hallucinations, on multiple occasions, or at least one in particular, a “woman” I assume, a pornstar, “Sat” on my erection member. I kind of remember that vividly, and, if they or she wasn’t just a figment of my imagination, but rather a wave form created by unknown technology (unknown to me) I can see a scenario where someone existing outside of you, yet “haunting” you could effect another man’s phallus.
That’s not hard to imagine, what hard is having to constantly recognize and get over the feelings that well up when I hear/think about this hit.
