Formerly, I guess there's always exceptions but usually the OM is just a fantasy. What I mean is that the Om is nothing but chemicals and a teenage idea of romance.
dont kid yourself. its usually because he "does it" for her. he's excitement. i bet you never watched a video about coral reefs or went to the aquarium and took notice of how some fish are red others blue, some have big fins they can expand, others are speedy and quick. its all about attracting a mate. ecology. chemicals, pheromones, enzymatic reactions sure blame it on them. true, the scent of a woman makes me horny. attraction. heck, there are probably multiple genes for having the propensity to desire multiple sex partners as well as smelling so good. lets blame it on watson and crick. mendel even. and fabio.
but, it all comes down to attraction and stimulating desire. and as a male that is your responsibility. enjoy.
btw, good friday is a great night to take someone out for a fish fry. lol.
if you dont like fish, birds are even better, although you never hear anyone say, there are alot of others birds in the sky. interesting thing you can see with birds, if you sit and watch birds long enough, you will notice how when a male comes in to mate with a female and the female isn't attracted to him and they don't do the jamboni off he flies to another part of his territory and another potential mate. they really dont waste time when the gettin' is good. nor do they sit around and wait for the female to change her mind or harass her after she gives the hint. they are busy and life is short. eventually usually she becomes attracted. maybe his colors get brighter or he smells better when he's out being attractive. interesting.
