dave told me that there are guys like that at the gloryhole and they can just keep going. he showed me one video where a guy came three times in about 10 minutes! i've never had one of those before. most guys are one and done but that's fine.
Don't ever try to compare yourself to men in porn. They are not "most guys." They are .01% with the biggest cocks and have the best cock control. Plus there's always performance enhancing *****.
