Non hormonal birth control options?

Question

A few month ago, side effects from the Nuva ring sent me to the ER (this was mostly because of heart palpitations and chest pain from dangerously low b12 levels). Since then, I’ve been off of birth control and have been taking b12 supplements. 
Because of that, I don’t want to try any kind of hormonal birth control (especially kinds that are difficult to remove quickly). My boyfriend and I have been mostly abstinent or we occasionally use the cycle method with spermicide, although the spermicide does irritate me a little. We don’t use condoms because they’re too irritating. 
Does anyone have any recommendations for non-hormonal birth control other than condoms or spermicide?

Answer

Copper IUD. And the hormonal IUD would be ok too because there is no estrogen and not only that but everything stays in the uterus

Answer

Have you tried non-latex condoms? The irritation could be caused by an allergy. And yes, you can be allergic down there but not anywhere else. Your options get sort of limited if you rule out hormones+(all)condoms+spermicide.
