For the hottest/most hardcore vids or hentai, I can masturbate a hundred times. I remember masturbating to Nanami's (Suikoden 2) awesome ass by Factory K a dozen times, and that's just a single picture. However, I do like variety.
As for girlfriends, I prefer loving one woman exclusively too, and I would, if I found one that's good enough for me, but I've been unsuccessful so far.
