If you tried to fuck me for 2 days of rough sex I'd be pushing you out of the door after the first 6 hours because I'd be in pain. Either you're not really having rough sex or you're at least stopping for some time periodically during that 48 hour period, or neither of you would have any skin left if nothing else.
It all really depends on timing, doesn't it? I don't really care whether He stays hard for 2 days at a time as long as He's with me and joining in with all of the important bits (and that could be with His mouth or fingers, or with a toy). Over the course of 2 days we may both have be in double figures for number of orgasms, but that doesn't mean that we keep going for the whole 2 days.
Marathon sessions are all very well, but every now and then you do need to have a break to eat, drink or sleep, and during that time erections don't really matter at all.
I did once have a bet with a boyfriend over a box of After Eights. He managed it but the focus was completely wrong and I vowed never to do that again as numbers are irrelevant. You fuck when you want to fuck and stop when you want to stop.
You are right, about 3 or 4x is about the max for us in one day with my husband having an orgasm each time...but since my man can make me cum more times then I can count in one session, I am more then satisfied. Besides, it's not all about his dick getting hard that satisfies me.
When I exhaust one guy, I usually have one or two more waiting in the wings. Having sex with just one guy for two days continuously would get boring and painful.
I've had a few guys who could keep themselves from cumming and fucked me continuously for 5 or 6 hours. Changing positions from time to time. Fortunately I don't have the same restrictions so I came many times. The only times I went longer than that was with multiple partners, and yes I was quite sore afterwards. It was worth it though for the experience.
