Not sure how much help I will be but.... I've never taken any birth controls either. Don't like all the negative side effects that I hear about (especially long term effects), plus they aren't always effective as you can still get pregnant. Although, same goes for condoms as well. But--Condoms have no side effects.

Trojan makes non-latex condoms (Trojan Supra). Lifestyles SKYN are also non-latex.
