Hi @ggplex,
Difficult to answer without knowing how experienced you are with women, so take what you want in what I write.
I call frame what you call vibe. It may be due to the fact you are projecting two different vibes (starkq vs emperor).
It seems that you have more success with women thanks to the sub, but more exposure to women lead to more learning opportunities and maybe you meet new type of women you are not used to.
Have a look at blackdragon aka Caleb Carr blog he explains more about frames in relationship and understanding women.
In order to be considered as sex material you NEVER verbalise it if not asked (twice) but you need to SHOW it : detached of (sexual) outcomes, VERY sexual when together but low interest when not together (low initiation of text/call but be 100% with her when you can talk her), target to go to sex within 3 dates (or a good sign of engagement kiss/blowjob depending on the type of girl), only fun dates, soft next quickly if she messes up or refuses to have sex, zero pressure zero anger toward her, never force for sex, never negociate to have sex.
and you don’t talk about being exclusive or player before she asks twice. The discussion HAS to come if the woman fancies you, so just be ready and handle it like a pro.
Your mindset : If she want to meet you, you set your availabilities, you are flexible but you dont bend your obligations for her. You dont play games, you desire her, you are comfortable with your sexuality, and there are plenty other opportunities, you go fast to sex but you are a gentleman.
Summary : read blackdragon blog or book on alpha 2.0 (even though the is quite extreme in my opinion) and think about the frame your are projecting because it is likely the cause.
Hope it helps,
