i was reading this thread on my blackberry today and couldn't remember my friggin password,lol. yea pretty much everything Nikki said, and one more thing. olive oil is your friend, it doesn't dissipate like the water base lubes and it doesn't burn for the woman like a petroleum lube can. and if she wants to go ass to mouth it can be a little more tasty as well with a good quality olive oil,lol.
the biggest difference i can tell btw vaginal and anal sex is with anal you can definitely feel what's going on with your woman, if you're hitting a good spot or a bad spot isn't hard to figure out,hahaha. and as for having somthing up my butt as well, yea i've done that too. i suggest if you're not married trying to hook up with a nurse for your next girlfriend and tell her you want a prostate massage while getting a blow job. AMAZING.
