Here's three tips: 1 -hot and sticky outside /humid indoors, use Johnson and Johnson baby powder. 2 -spank /whip it. Sometimes while I'm hard I slap my cock around a bit. I cup my hand and slap my cock into my hand some. Then maybe a little top end slaping. I get a bigger gasm from it being slightly stinging when I cum! Also I have a butt-plug with a horse tail whip on the other end. Works great gently whipping it around a bit -Pow! MMMhm!! 3 -Best of all is my "brinking technique"!!! I like to surf for free porn, or even ladies clothes sometimes. I'm already getting hard just being naked at my pc to start. Once I've found something that turns me on, I spank till I almost cum, then stop. I go and have a quick smoke outside, then return and start again. At the brink of cumming again, I stop and go get a beer, or just switch modes from anal porn to feet in socks porn. You start to get soft switching gears like that, but get hard again soon. I get alot of pre-cum ooze between hard, and limp over and over. I keep plenty of tissue on hand to dab. I once kept it up for 3 hours! When my cock was starting to get raw, I put my usual rag onto the floor to catch my spearm between my legs under the computer as usual. When I came I splattered my wall, sprayed the underside of my pc desk, hit my leg - AND Kept Cumming for a while after!! I guess the body thinks you need more spearm every time you brink and stop
