Licksipuckit is absolutely right but I also think that men can be easily put off if the woman's vibes aren't right.

"I love the way you look, you are so fucking sexy, it would be great to have sex with you sometime"
should, ideally, be sufficient for a woman to open her legs if she also fancied the guy saying this.
But reality is the opposite because honesty and straightforwardness are not appreciated.

honesty is the best policy and being up front and open is the best, women have great BS detectors and if youre trying to put one over them, they wont be inclined to open up to anyone, l think alcohol used to have a big part in it but now men have to be gentlemen and better people to get women horny *lix*

I'm not sure if thats a good way to ask that, but what i look for in a women that i want to be with, its work for you to get a women to open her legs, my wife, we were good friends for 8 years, and flirted and just best friends, we started that way, got to know one another she didnt open her leg for me right away nor did i want her too, and once we laid down together it was worth the wait, just be yourself, don't be too forward
