I crazy horny but I can't get a erection, I have 3 girl friends and I was doing fine having sex about 2 times per week... But recently I can't seem to get it up... And when I do it stays hard for only 10 seconds, by the time she hops on its still large but softer...
And rubbing it doesn't get...
running.... sprint for 1 minute, walk for 5, and do that 10 times, then run until you feel like your legs are going to fall off, then walk a lap and ur done day one, all thats left is the other 364 days of the year, BRING IT!
