broken condoms πŸ™„πŸ™„πŸ™„

so let's start by saying I'm highly allergic to latex. so stores around here don't have a large selection of non latex condoms. me and my boyfriend got Trojan bareskin nonlatex condoms. and yesterday we went through a whole box, every single one broke. so I had to get plan b, just in case anything went in me. like wtf. anyone know of some better non latex condoms, or why the fuck these broke!?
