I think that any strategy planned out or rehearsed has a chance of failing because it would be too robotic...it's like somebody reading a book on how to dance...while the natural dancers are out there fluid, and instintively rythmic...the guy who learned from a book is out there saying in his mind "1& 2&3& dip, slide & slide, twist and Split....people can tell...
Although I do feel this is solid advice, but if somebody doesn't play it all-naturAL..it will fail...
Women wanna have sex more than we do, they just don't wanna look like hoe getting down with you...so the smoother you make that transition the better chances you have of sealing the deal...
