The only dudes who ever mentioned aura to me waited until after I had sex with them to do it, and had a hard time taking the hint when I lost interest in them. I found them clingy and soft. Words like "aura" and "astral plane" are alarms for me. I flee. I have to admit some fault: I'm a great communicator at the beginning and throughout a casual relationship. When I want it to end, I'm kind of lame. I don't actually know how to dump guys. It's so awkward.
Barring the use of the word aura, I have no real problem with that kind of proposition, as long as I'm not offered money. I would just decline. I don't like getting hit on by strangers. When men I do not feel familiar with approach me, it makes me feel like I have no control over the situation, which feels scary. I leave. I prefer to make the first move. Probably the best way to get sex out of me when I was single was to be nearby, attractive, and make good eye contact. Eye contact would give me the confidence to come over and chat, and get a dude's number. I never fucked dudes I just met. I preferred to get to know them a little over the phone, and give them time to get their paperwork in order before hanging out with them, at which point I'd fuck them if they were not uptight about sex on a "first date".
How does being asked for sex differ from some random dude talking to me about my tits? Greatly! When being asked for sex, even if I can't wait to escape the conversation, at least I do not feel I have been reduced to a collection of nice body parts. Also, my individual experience comes into play. Men have actually come up to me and spoken to my breasts. I don't mean they were talking to me while staring into my cleavage. I mean literally addressing my boobies, as if they could respond. Fucking weirdos. So anyway, that colors my interactions with other men.
