Not that I'm an expert, but especially if you have anal you should use a condom. The backdoor is quite a bit more sensitive than the front, meaning that it isn't designed to give quite as readily and the membranes are much thinner (again, not designed for repeated withdrawl and entry) and more prone to damage. Chances of her getting a little raw back there and bleeding a little bit are pretty good, especially if she's new to it. A condom actually decreases that risk.

Plus, the ass's central purpose isn't sex. Even if she's sparkly clean, there are microscopic things that live back there that neither of you want getting into the wrong biological places.


Other than that, have a great fuckin' time.

One more piece of advice, you might want to pull one off early in the day so you don't bust a nut too early.
