I used to do something like that in the beginning of my pumping days, staying on a 2.5" cylinder with a heat pad for 2 hours at close to 10hg... I was about 5 1/4 girth, and pumped to over 6 1/2... it screws the erections, had to take cialis to make it operational, and it hurts to have sex with that huge blister of a donut... on top of that, couldn't let my wife see it , she would freak out, it looked too messed up... and that was a problem because she is a real bj queen, we always start with her sucking my cock and about 90% of the time I cum in her mouth, with some more oral in between changing positions... the first time she felt it pumped she said " it feels big today!" but sometimes she would noticed it when I was taking vimax without her knowing it... I keep telling her that was because she was making me so excited that day! she was very naive and a virgin when we married and never been with another guy before so she believes me... I keep on pumping but now that I found [words=http://www.mattersofsize.com/join-now.html]MOS[/words] I know better not to go over 5hg and keep the sets under 20 min. I've gained about a half inch in girth and about 3/4 in lenght in the 6 months since I became a member of this site, with a combination of DLD exercices, clamping and pumping... I usually pump twice a week now , can fill a 2" tube in a couple of low pressure sets without the donut, so she can suck on that fattie later! she loves that the head is getting bigger too.. DLD's work on this site is invaluable, I WILL buy some of his stuff to help him out as soon as work starts again and I get some money.... keep on the good work guys!!
