I don't really have anything to offer. I have never been able to manifest any sort of romantic relationship, casual sex, not even a date. I really don't understand why either. I can manifest other things fairly easily. I am quite happy on my own, so I'm not needy or overly attached to the outcome, but I am rather curious at to why romantic intentions always to seem to fizzle and go nowhere.
I think you are doing pretty good if you are able to manifest anything in the romance department. It seems to me to be very difficult. Maybe you just need a bit more practice and some fine tuning.
When you manage to nail it, please post what you did. I would be quite interested to try it for myself.
