You can flirt without being sexual or crude. Non verbals....Eye contact and smile. Sincere, light hearted, compliments.
Start with being more physically expressive with family...hug your siblings, cousins and parents. Give your grandmother that cheek kiss that you always dreaded. This actually creates a base line of physicality that you feel more comfortable with.
Work in the
bro-hugs with your male friends. Be clear if you are shaking hands or doing the hi five hand clasp. Signal early and commit to it.
It's not so much flirting with friends and acquaintances as being more
familiar. When you are in a social circle you become more familiar to give interested women the opportunity to show their interest without fear of rejection. The burden is on you to determine if it is genuine romantic interest, or familial affection. This takes repetition to recognize.
You know you have created a good base line when you greet some friends who introduce a new woman and she greets you in the same hugging fashion as you engaged your common friends. Thus the touch barrier has been broken... add in some good eye contact and incidental physical contact and pretty soon she is grabbing your arm and laughing. You invite that and reward it rather than pushing it yourself.
I'm not flirty I'm warm and welcoming. I let the girl be flirty and I reward it. With attention.
I hope that is a clearer explanation.
Rather than trying to tailor your approach to the company, set a tone with every one and see what interest pops up.
Some examples:
I was at dinner with my parents where my father was receiving an award. At our table was another family with 2 daughters a little younger than me. We got to talking and I was, as my mother puts it, "My usual charming self" and they started turning up the flirt. They were almost competing with each other
for my attention . Made my mother quite upset and she snapped at them "You know he has a wife and two daughters at home don't you?"
In my running group I have a core of people I've known for years. When I arrive we all hug and greet each other warmly. there was a couple of newer runners in the group so I engaged them and deep dived them and got them talking about themselves. One of them kept coming back and I made sure to greet her by name before and after. Lots of eye contact and smiles, and finally she approached me about my availability. I could have asked her out a couple weeks earlier but I wasn't interested anymore and ironically when I engaged her less, she got more aggressive.
