I'm real interested in the "wang exercises".
Someone above said:
YOu don't have to masturbate every day.
You've got to be kidding!
I had a urologist tell me I should ejaculate at least once a day. It has done a great deal for my general disposition. My only regret is that I didn't get him to write that onto a prescription form that I could show my girlfriends over the years.
I may be older than most of you. I've been jerking and fucking for over 50 years now. And, the fact it, I can't hit the bed post anymore. I used to be able to jerk off laying on my back and shoot it over my head. I think age has something to do with it. But, when I was younger I wasn't cumming all the time. I was taught it was wrong, so would hold off until I could't stand it. It would indeed be interesting to go a week without sex to see what it was like, but the fact is, I like cumming too much to hold off. (And the fact is, at my age, there is always the concern that it might be my last tango!)
In any case, I don't think my orgasm is any different if the load is different. Doc put me on Flomax once. Nothing came out, but I still had an orgasm. (That was real weird, and I stopped taking that.)
Also, there is a great book out there called "Sperm Wars" (Robin Baker). It indicates the semen load is different depending upon the partner. A new girl definitely will produce a bigger load, as will a regular girl if you think someone else is about to fuck her. Something about the semen trying to make the conception, and block the other guy. I don't know how that would play into just jerking.
There really should be a government grant to study this. Who was that scientist back in Indiana that studied sex?
One other thing: I find I can't masturbate as easily if I'm not getting intercourse regular. If I have good sex at night, I can beat off real easy, and with a good splash, the next morning. If my wife is out of town and I'm not getting sex, jerking off is more work and sometimes less successful. So maybe the load has something to do with attitude. Jerking in frustration may be less fruitful than jerking while full of good memory of recent pleasure.
