I have always thought, and have had many people concur over the years, when I asked, that cum smells very much like the mold on a fine, aged Brie cheese. Cum tastes so sweet and delicious, I think, and I often take a whiff of some new Brie I just purchased, for that wonderful memory.

And, while I'm not a biologist, I believe that the almost instantaneous loss of interest in cum, or other sex play activities, is an evolutionary aspect of most male mammals, not just humans, that increase the chances of spreading the genes; as the females were/are still 'hot', and ready to accept another male's 'entrance'. Check out, sometime, a ring of howling male cats encircling a female in heat, and you will see a good example--they fight each other until they cum in her, then couldn't care less right after, if another male gets to her.

Add me to the list
I like to do the legs over head thing and jerk off shooting in my open mouth.
PS licking a cum filled cunt or tongue kissing her after cumming is great fun too
