That really sucks. Also, you can't use it while your girlfriend is on her period.

I suggest a product like Conceptrol or VCF (vaginal spermicides). I've been using Conceptrol with my husband for the past 8 years and we have not had any pregnancy scares. The only problem with the stuff is that it can be messy, but hey, sex is messy anyway right? Vaginal spermicides are more effective than they used to be, so perhaps you should look in to it.
