Wow, I have to be honest, anything more than, 15 to 30 minutes of actual penetration time starts to get annoying. Like, "Holy shit, I can't cum. Please, please! Lets do this... I'm a cashew."
In all reallity, though usually with my confortable partner of 8 years, the whole thing can take not long at all. There is little needed of trying to impress one another with big numbers on the clock.
On that same token, we both know what we both need, and give of sufficiently. Sometimes we'll spend 10 minutes just kissing, then I'll go down on her until she gets off twice, then yeah the sex doesn't need to take long, as she's already in cum over-and-over-again-mode.
for those that say multiple hours - You all must have some Krytox, high-capability, government only lube or something, because I know after 30 minutes at best of pumping my wife and I would be begging for it to stop. We tend to get raw, but maybe thats because my 3"x1/2" penis can't keep a good lube seal.
