A few days ago i was opened a hb8 with an opinion opener. what kind of guy do you like? a muscular guy with a bad face or a normal guy with a nice face? she replied by why the hell are you asking me? I left because she was wasting my time. How would i respond to that?

Perhaps you should open with opinion openers which are less sexually oriented / flavored.

Anyway, I'd respond with

[ha ha ha] Oh my, you're such a little peace of shit. I eat girls like you for breakfast.
HB: And I eat them for lunch.
You: I'm already stuffed.

I think this is something similar to what Mystery did in these kind of situations.

Your issue could've been that you were too direct to her haha every girl is different in that aspect

you should respond to this by having a reason why, she wants to know what your intentions are, this is not a shit test, and why you would leave set before being rejected is weird, communicate with people when they ask you questions, she wouldn't kill you for saying ''because I find women like you very attractive, and I want to see if it is better to have a good looking face, or a good looking body''

if you are too nervous to be honest, then you can say anything to justify her question, you can even be irrational, at least communicate with her, and there is no point in leaving a set unless, you have something else to do at that time that you were going to do anyways, you are clearly and completely rejected this doesn't mean you feel she is cold, or you are uncomfortable, seriously wait until the point either she leaves, or tells you to leave, or clearly states she is not interested in you, and I have a boyfriend is not a rejection, it can be, but you should push through the set and let her know this isn't an issue for you, unless it goes agaisnt your values and ethics to do so

Thanks guys, i forgot to mention she is shy, these types of girls arn't that playful at the start. How would i get past that?
