^ yes, the instincts just take over. With a partner might be a bit chaotic you are right, so its best best use is probably for oneric activities. Without a focus you just feel sort of plastered all over. But with a focused and energetic activity, the material seems very malleable and its effects I FIND anyway form themselves along with the activity. If you just sit there waiting for "stuff to happen" yea it is probably just kind of bleh. This is one you MUST CONSCIOUSLY *DO* SOMETHING WITH.
And yes it does combine nicely with other things. Ive added it to Methylone after that has stabilized at its peak with great highly euphoric effects and no notable body issues... is intense though so be forewarned to expect, um, alotta G's (g-forces, gravity, acceleration, etc)
