Am I being neurotic or do I have reason?

[Sanctuary]

^ Pheromones!

[Primo]

Pheremones would be if you backed up a female with curvy hips and a tight ass, her lycra sweat stained from pilates into my (or any other guy's) face :-P Ya, my heart rate would speed up and my nuts would get tight real quick :-)

Now turning her around and letting me see if I'm attracted to the rest of her, if we have a strong mental connection and hit it off on a sensual level, that's what makes chemistry.

Anyway, I just don't want the OP to think that being intimate early in a relationship is wrong or increases the chance of failure. No way ! If it's there, it's there, it ain't going anywhere :-)
