Why not just slow down?

I don't want to sound like I'm bragging, but if a girl gets me to cum in under 5 minutes, it's because she's fucking lucky, or I wanked it a few times just before the point of cumming, specifically for the purpose of cumming fast in bed. It's not like these girls suck in bed either, i just know how to keep myself just before the "point of no return". Feels fuckin great.
