Pheromones themselves have no detectable scent....they're more like airborne chemicals, but have no scent....that's what I read anyway.
I think they are added to some men's and women's colognes.....but not all....and the men's pheromones are different from the women's.

I have only noticed fresh spunk to smell a little bit fishy....but not a strong smell at all.....but I'm talking about less than say....30 minutes after sex.

Actually, no matter how clean I was when the sex began, I am the one who smells fishy with it inside me.

For some ridiculous reason when we were dating we saved a "load" in a small jar.
When we opened it a week later it was "OMG !!!....throw that shit out !"
LOL
