I only use condoms coated with spermicide. I have never had a problem with them. Some people do have allergies to spermicide, although that isn't the norm. Most condoms (at least around where I live) have spermicide. It's not as easy to find ones that don't have it.

The main ingredient in spermicides which has taken so much heat is nonoxynol-9. There is still a lot of controversy about it. Some people say it's dangerous, others are all for it. You could look into this site more. I have only looked at it a little. It looks like they sell all kinds of condoms, none of which have nonoxynol-9:

so it is up to you as far as what side of the debate you want to take with nonoxynol-9. The main issue that some people have with n-9 is that it may increase the chances of getting hiv. In some studies, researchers found that participants who used n-9 were more likely to get hiv.

Have you considered birth cotnrol pill use at all?

Condoms alone can break, and it is always good to have a back-up.

In case you are under 18, you do not need parental consent, and at places like planned parenthood, it can be free =)

also, if a condom breaks, you can use the morning after pill up to 5 days after sex, but it is most effective within 3 days.
