I would best describe my average time for sex as "efficient", haha. I kid, I kid.
Crazy how all these people are having sex for more than an hour at a time though, I would estimate I'm done after about 30-40 minutes almost every time if we're talking about intercourse. If I haven't seen my girlfriend in a while and haven't....shall we say.....prepared myself properly......it's messy and pretty quick, haha.
Hopefully I haven't been lied to my whole life, but the women I've been with say that they get sore after more than 45 minutes or so, both vaginally and body wise. I'm not packing all that much, but two to three hours? Jesus......that's gotta be uncomfortable after a while, no?
