Attract your perfect submissive sexual lover.

[SargeMaximus]

I have found that more than 8 hours of sex is painful the next day, and the one time I spent ~12 hours having sex, we were in so much pain we couldn't get out of bed for days. I suggest that instead of trying to kill her and her vagina with an endless stamina marathon, you go for learning how to give her enough pleasure to satisfy her in a reasonable amount of time. Most women I know would rather you please them a to their desired degree during 45 minutes to perhaps 3-4 hours of sex at most, (and the latter is usually rare) than that you spend hours and hours at it. The exceptions, of course, are if she's a nympho, she's your perfect lover, and possibly if she's ovulating. The 8+ hour marathons I have done were all done with my perfect lover, who was a nympho, while she was ovulating.

Sounds... awesome...

I need a nympho then AND I need those ejaculation delay pills. Seriously, 12 hours of sex!? Totally awesome. I want 24 myself but it doesn't have to be with one woman. I can finish one girl, then go find another.
