Condoms and Lube for Sensitive Vs

Liesel
So I'm extremely sensitive down south. I'm allergic to spermicide and the one time I tried flavored lube, it was not good. I can't use arousal enhancers (like KY yours and mine) or anything extra. I'm allergic to the lube on Magnums and some Trojans. Recently I've developed an allergy/averse reaction to my favorite lube, KY water-based jelly, which is supposed to be the best for sensitives. 
So what I wanna know is do any of y'all have the same issues? What condoms and lube do you use? Should I try a silicon based lube? I just don't want to give up sex but I don't want to get pregnant rn or have chafing.
