I don't think Sweetrush was intending to offend, just pointing out your options since you both (mainly your guy) seem to not actually trust the birth control fully, and wanted a backup method. Your options are kinda limited, and since pregnancy seems to be the factor you are both worried about, one of the options is, indeed, to stop engaging in those specific acts of sex that have a risk of pregnancy. It's not meant to offend, she's simply pointing it out as an option, since barrier methods are mostly ruled out for you guys.

Condoms are ruled out, he can't use them. Spermicides are highly irritating for most women, and messy, so they're mostly out it seems. Diaphrams use spermicides, so that's out too. Female condoms maybe? There really aren't any other backup methods to be had, unfortunately, if he doesn't like/can't use condoms. :/
