I don't know if you do anal play but there is more of a risk of injury during anal sex compared to vaginal sex. http://en.wikipedia.org/wiki/Anal_sex Just be careful with anal. I would suggest that a condom goes on anything going in anus...and don't go from anus and then to vagina or mouth...don't want an infection! Also, you can still transfer hpv and other stds even with a condom but it's less likely with one on.
