Wow! So anyway Marley you asked if your need for seed is unusual... but, you asked a bunch of guys
I for one would like to believe that these sexual wants and needs all serve to help us procreate.. Just like how the media always shove this emaciated ideal of beauty down our throats when I figure at least 80% of men would perfer your full child bearing hips(adjust that figure +2% or -2% for guys that are confused. let's assume the other 20% are gay)
I wil tell you one thing I have noticed about women and semen, THERE SEEMS TO BE NO MIDDLE GROUND ON SEMEN.. A chick will either embrace it accept it willingly almost as a display of affection..OR have no use for it at all and avoid it like the plague No in between..
