What are some other ways besides stop-and-go that could make me last longer.
Improve how long I last
that's a tough one. I take this advice straight out of Chuck Palahniuk(author of Fight Club)'s book "Choke"- whenever the guy has sex with a hot chick, he thinks about dead rats, compost heaps and multiple car pileups to keep from cumming 2 early. Or just think of a real fat chic or some 1's grandma. Never tried it, but sounds like it helps.
Mental approach seems to work for me. At the moment I've settled on memory of me catching this cat in a cage. Pretty random but it seems to work. I still feel like I'm going to come but it just stays there. Great feelings actually.
