No difference. Tearing or leaking data are about the the same and very low. The real test is sperm and semen in the vagina. Because this most commonly results from sperm swimming around the open end, there is no difference. I recommend with either that vaginal spermicide be used.
The data supporting the link that Demon gives you are accurate but the difference Alice describes has less effectiveness than not withdrawing immediately after ejaculation. VAGINAL SPERMICIDE!!!!
Actually, there are four commonly used chemicals: Nonoxynol-9, Octoxynol-9, menfegol and benzalkonium chloride. Not all of these are available everywhere in the world. Some systems such as the sponge uses a combination.
The most common, by far, is Nonoxynol-9. It is also the one that is implicated in most allergies. It is a detergent (as is Octoxynol) and women with an allergy to detergents should not use these. You can search the various spermicidal potions on the net - jelly, foam, film, suppository, tablet. Find one with a different chemical than the spermicide she reacted to and try it out.
Many people do not consider condoms to be adequate protection alone. Spermicide plus a condom greatly reduces the risk.
I found this link
I am sure Brandye will have the answer :)
