Thanks for the suggestions so far, guys.
@Bchung and @austin821, I'm not so sure about tranny's or granny's. But then my mom did tell me to try at least everything once. But then again, I think she meant eating my vegetables.
@zebra, I'm definitely trying to avoid this one. I've half fallen a couple of times, but luckily I'm the kind of guy who would get bored.
@anabikumi, i do watch a lot of porn... but any specific suggestions?
