Sperm volume, trajectory and speed - an unscientific pole (pun intended)

Roissy did a post once upon a time on the volume of sperm and speed at which it exited being relative to the hotness of the babe he was banging.  I remember being intrigued by it.  I'm not searching his posts to find it, maybe someone remembers?

Anywhoo...

I was dating a man who I had a very comfortable, open communication with as well as a very hot sex life, so I felt I could ask him if he noticed a difference depending on the hotness factor of the chick he was with.  I felt I'd rank up there on the scale of hot sex he'd had, so any answer he gave would not be to protect my feelings. 

Here's what he said:

If you wait awhile between sexual encounters or masturbating you will have more ejaculate.  He said he really never tested this one out too thoroughly because he couldn't go a week without one or the other or both.

If your mind is not fully invested in the sex that's happening then you won't come as hard.  He said it's not always about the hotness factor of the chick - it's about what's happening in your life at the moment. 

He said even mastabory sex could be good or not as good depending on where your mind is.  I find this to be true myself.  Sometimes this means is good for stress relief and great if done quickly, othertimes it's best if it's drawn out and builds the orgasm.  Sex with a partner is the same. 

He didn't seem to think the hotness factor was as much of a big deal as Roissy had made it.  Mind you maybe he only dates hot chicks.  (heh).
