What everyone else said about. Although, I can’t see how pumping for 4 minutes, twice, will do anything. There’s pretty much zero change in size unless you’re pumping for over 30 minutes and you’ve got fluid buildup…then you’ll have temporary girth gains. I’ve added an extra inch of girth through pumping, but I usually do it hours before and wear a cock ring to keep the fluid buildup there. Of course, I still have to wear the ring for sex after, but it’s fun for a temporary change. I fight with ED issues anyway, so sometimes I’d rather have a little extra girth when I’m having erection issues…it gives her something to grip on to. Plus, sometimes the extra friction and the thought of the bigger size helps the mental aspect of ED.
