A man can flirt. Has the balls to do it. You need to first build a connection. Get to know her a bit. Throw in some funny sexual innuendos to show your fun and that you are confident to bring up sex as it isn´t a big deal. If she sees it isn´t a big deal for you, she´ll put you as a high value as she will think you get laid a lot. Then every now again, touch her arm, back of neck, hug her. If she does it back to you, golden! If not but she doesnt move away, that is also ok. Step back and wait a couple minutes before doing it again. If she physically takes a step away, you also move back and build a better connection/vibe
