CONDOMS

My boyfriend is allergic to condoms, it feels like his dick is burning off when we use them but we don't wish to continue with withdrawal because I can't get on birth control. It's too scary waiting for my period. We are unsure about which he's allergic to, the latex or spermicide so we'd like to get one without either. Can we get a suggestion as to what we should get? Something that can be bought at a Walgreens or Walmart?
